Gitter Desktop App for testing the API

readme

Alora,
Here is some code I quickly hacked up to help somebody in the gitterHQ/gitter channel in Gitter who was having a problem with his client.  This example shows how you can play with the Gitter desktop app and hack quickly against the Gitter API.
It's not pretty - quick and dirty but it should work and gives you an idea of how you can play in the desktop app.

Open up the desktop app and select the Gitter Menu -> developer tools.  If the desktop app crashes at this point - you have multiple instances of Gitter open - the desktop app doesn't always close down properly.. On Windows open up the task manager and kill any lingering processes.  Start gitter again and try to open the dev tools.

When it's open.. click console and then you can start pasting from the code from the JS.

It's lightly documented and it should work but your milage may vary.
It should be obvious what it's doing.

Any headaches or questions - ask in the gitterHQ/gitter tab
