Summary:
Until now, we've been hiding transactions beneath the surface. When you call persistModel, you're implicitly creating a transaction.
You could explicitly create them with `atomically`..., but there were several critical problems that are fixed in this diff:
- Calling persistModel / unpersistModel within a transaction could cause the DatabaseStore to trigger. This could result in other parts of the app making queries /during/
the transaction, potentially before the COMMIT occurred and saved the changes. The new, explicit inTransaction syntax holds all changes until after COMMIT and then triggers.
- Calling atomically and then calling persistModel inside that resulted in us having to check whether a transaction was present and was gross.
- Many parts of the code ran extensive logic inside a promise chained within `atomically`:
BAD:
```
DatabaseStore.atomically =>
DatabaseStore.persistModel(draft) =>
GoMakeANetworkRequestThatReturnsAPromise
```
OVERWHELMINGLY BETTER:
```
DatabaseStore.inTransaction (t) =>
t.persistModel(draft)
.then =>
GoMakeANetworkRequestThatReturnsAPromise
```
Having explicit transactions also puts us on equal footing with Sequelize and other ORMs. Note that you /have/ to call DatabaseStore.inTransaction (t) =>. There is no other way to access the methods that let you alter the database. :-)
Other changes:
- This diff removes Message.labels and the Message-Labels table. We weren't using Message-level labels anywhere, and the table could grow very large.
- This diff changes the page size during initial sync from 250 => 200 in an effort to make transactions a bit faster.

Tests work now
Clean up argument variables
Rename list manager and get rid of old spec-helper methods
Extract out time overrides from spec-helper
Spectron test for contenteditable
fix spec exit codes and boot mode
fix(spec): cleanup N1.sh and make specs fail with exit code 1
Revert tests and get it working in window
Move to spec_integration and add window load tester
Specs pass. Console logs still in
Remove console logs

Make integrated unit test runner
feat(tests): adding integration tests
Summary:
The /spectron folder got moved to /spec_integration
There are now unit tests (the old ones) run via the renamed
`script/grunt run-unit-tests`
There are now integration tests run via the command `script/grunt
run-integration-tests`.
There are two types of integration tests:
1. Tests that operate on the whole app via Selenium/Chromedriver. These
tests have access to Spectron APIs but do NOT have access to any JS object
running inside the application. See the `app-boot-spec.es6` for an example
of these tests. This is tricky because we want to test the Main window,
but Spectron may latch onto any other of our loading windows. Code in
`integration-helper` give us an API that finds and loads the main window
so we can test it
2. Tests that run in the unit test suite that need Spectron to perform
integration-like behavior. These are the contentedtiable specs. The
Spectron server is accessed from the app and can be used to trigger
actions on the running app, from the app. These tests use the
windowed-test runner so Spectron can identify whether the tests have
completed, passed, or failed. Unfortunately Spectron can't access the logs
, nor the exit code of the test script thereby forcing us to parse the
HTML DOM. (Note this is still a WIP)
I also revamped the `N1.sh` file when getting the launch arguments to work
properly. It's much cleaner. We didn't need most of the data.

Move to DOm mutation
Spell as `subtree` not `subTree`
- Upgrade node-sqlite3 from patched 3.0.2 to mainline 3.1.0
- Upgrade Electron to 0.30.8: NOTE: This is the latest in the 0.30 line.
The 0.31+ line did a Chrome upgrade that we want to save for a later
day. We've had a history of serious instabilities with these upgrades
and are doing them conservatively
- Upgrade coffee-script from 1.9.0 to 1.10.0
- Package updates in /build folder
node-gyp header layout change in node v4, causes package builds to fail.
This change forces node-gyp to download the correct version of node so
native extensions can be built.
