Summary:
This diff is designed to dramatically speed up new window load time for
all window types and reduce memory consumption of our hot windows.
Before this diff, windows loaded in ~3 seconds. They now boot in a couple
hundred milliseconds without requiring to keep hot windows around for
each and every type of popout window we want to load quickly.
One of the largest bottlenecks was the `require`ing and initializing of
everything in `NylasExports`.
I changed `NylasExports` to be entirely lazily-loaded. Drafts and tasks
now register their constructors with a `StoreRegistry` and the
`TaskRegistry`. This lets us explicitly choose a time to activate these
stores in the window initalization instead of whenever nylas-exports
happens to be required first.
Before, NylasExports was required first when components were first
rendering. This made initial render extremely slow and made the proposed
time picker popout slow.
By moving require into the very initial window boot, we can create a new
scheme of hot windows that are "half loaded". All of the expensive
require-ing and store initialization is done. All we need to do is
activate the packages for just the one window.
This means that the hot window scheme needs to fundamentally change from
have fully pre-loaded windows, to having half-loaded empty hot windows
that can get their window props overridden again.
This led to a major refactor of the WindowManager to support this new
window scheme.
Along the way the API of WindowManager was significantly simplifed.
Instead of a bunch of special-cased windows, there are now consistent
interfaces to get and `ensure` windows are created and displayed. This
DRYed up a lot of repeated logic around showing or creating core windows.
This also allowed the consolidation of the core window configurations into
one place for much easier reasoning about what's getting booted up.
When a hot window goes "live" and gets populated, we simply change the
`windowType`. This now re-triggers the loading of all of the packages for
the window. All of the loading time is now just for the packages that
window requires since core Nylas is there thanks to the hot window
mechanism.
Unfortunately loading all of the packages for the composer was still
unnaceptably slow. The major issue was that all of the composer plugins
were taking a long time to process and initialize. The solution was to
have the main composer load first, then trigger another window load
settings change to change the `windowType` that loads in all of the
plugins.
Another major bottleneck was the `RetinaImg` name lookup on disk. This
requires traversing the entire static folder synchronously on boot. This
is now done once when the main window loads and saved in a cache in the
browser process. Any secondary windows simply ask the backend for this
cache and save the filesystem access time.
The Paper Doc below is the current set of manual tests I'm doing to make
sure no window interactions (there are a lot of them!) regressed.

Summary:
This diff implements a behavior change described in https://github.com/nylas/N1/issues/1722.
Reply buttons should prefer to focus an existing draft in reply to the same message, if one is pristine, altering it as necessary to switch between reply / reply-all. If no pristine reply is already there, it creates one.
Reply keyboard shortcuts should do the same, but more strictly - the shortcuts should switch between reply / reply-all for an existing draft regardless of whether it's pristine.
This diff also cleans up the DraftStore and moves all the draft creation itself to a new DraftFactory object. This makes it much easier to see what's going on in the DraftStore, and I also refactored away the "newMessageWithContext" method, which was breaking the logic for Reply vs Forward between a bunch of different helper methods and was hard to follow.
Test Plan: They're all wrecked. Will fix after concept is greenlighted
