Electron 0.35.1 includes the tray fixes we contributed last week but also includes API restructuring and improvements. Most importantly, modules from electron are now imported via `require('electron')`
Summary:
This diff replaces the UnreadCountStore with a better approach that is able to track unread counts for all folders/labels without continuous (and cripplingly slow) SELECT COUNT(*) queries.
When models are written to the database, we currently don't send out notifications with the "previous" state of those objects in the database. This makes it hard to determine how to update counters. (In the future, we may need to do this for live queries). Unfortunately, getting the "previous" state is going to be very hard, because multiple windows write to the database and the "previous" state we have might be outdated. We'd almost have to run a "SELECT" right before every "REPLACE INTO".
I created an API that allows you to register observers around persistModel and unpersistModel. With this API, you can run queries before and after the database changes are made and pluck just the "before" state you're interested in.
The `ThreadCountsStore` uses this API to determine the impact of persisting a set of threads on the unread counts of different labels. Before the threads are saved, it says "how much do these thread IDs contribute to unread counts currently?". After the write is complete it looks at the models and computes the difference between the old count impact and the new count impact, and updates the counters.
I decided not to attach the unread count to the Label objects themselves because 1) they update frequently and 2) most things observing the DatabaseStore for categories do not care about counts, so they would be updating unnecessarily.
The AccountSidebar now listens to the ThreadCountsStore as well as the CategoryStore, and there's a new preference in the General tab for turning off the counts.
Test Plan: Tests are a work in progress, want to get feedback first!

Summary:
We send database `trigger()` events through the ActionBrige to all windows of the app. This means that during initial sync, we're serializing, IPCing and unserializing thousands of models a minute x "N" windows.
This diff converts the payload of the trigger method into an actual class that implements a custom toJSON. It converts the impacted `objects` into a string, and doesn't deserialize them until it's asked.
Bottom line: this means that in many scenarios, we can avoid creating Contact models, etc. in composer windows only to broadcast them and then gc them.
Test Plan: No new tests yet, but this should definitel be tested. #willfix.

The Promise chain we were creating was never cleared and created a memory

Summary:
Fixes T4291
If I made a final edit to a pre-existing draft and sent, we'd queue a
`SyncbackDraftTask` before a `SendDraftTask`. This is important because
since we have a valid draft `server_id`, the `SendDraftTask` will send by
server_id, not by POSTing the whole body.
If the `SyncbackDraftTask` fails, then we had a very serious issue whereby
the `SendDraftTask` would keep on sending. Unfortunately the server never
got the latest changes and sent the wrong version of the draft. This
incorrect version would show up later when the `/send` endpoint returned
the message that got actually sent.
The solution was to make any queued `SendDraftTask` fail if a dependent
`SyncbackDraftTask` failed.
This meant we needed to make the requirements for `shouldWaitForTask`
stricter, and block if tasks failed.
Unfortunatley there was no infrastructure in place to do this.
The first change was to change `shouldWaitForTask` to `isDependentTask`.
If we're going to fail when a dependent task fails, I wanted the method
name to reflect this.
Now, if a dependent task fails, we recursively check the dependency tree
(and check for cycles) and `dequeue` anything that needed that to succeed.
I chose `dequeue` as the default action because it seemed as though all
current uses of `shouldWaitForTask` really should bail if their
dependencies fail. It's possible you don't want your task dequeued in this
dependency case. You can return the special `Task.DO_NOT_DEQUEUE_ME`
constant from the `onDependentTaskError` method.
When a task gets dequeued because of the reason above, the
`onDependentTaskError` callback gets fired. This gives tasks like the
`SendDraftTask` a chance to notify the user that it bailed. Not all tasks
need to notify.
The next big issue was a better way to determine if a task truely errored
to the point that we need to dequeue dependencies. In the Developer Status
area we were showing tasks that had errored as "Green" because we caught
the error and resolved with `Task.Status.Finished`. This used to be fine
since nothing life-or-death cared if a task errored or not. Now that it
might cause abortions down the line, we needed a more robust method then
this.
For one I changed `Task.Status.Finished` to a variety of finish types
including `Task.Status.Success`. The way you "error" out is to `throw` or
`Promise.reject` an `Error` object from the `performRemote` method. This
allows us to propagate API errors up, and acts as a safety net that can
catch any malformed code or unexpected responses.
The developer bar now shows a much richer set of statuses instead of a
binary one, which was REALLY helpful in debugging this. We also record
when a Task got dequeued because of the conditions introduced here.
Once all this was working we still had an issue of sending old drafts.
If after a `SyncbackDraftTask` failed, now we'd block the send and notify
the users as such. However, if we tried to send again, there was a
separate issue whereby we wouldn't queue another `SyncbackDraftTask` to
update the server with the latest information. Since our changes were
persisted to the DB, we thought we had no changes, and therefore didn't
need to queue a `SyncbackDraftTask`.
The fix to this is to always force the creation of a `SyncbackDraftTask`
before send regardless of the state of the `DraftStoreProxy`.
