[1] Kelp GUI: we need an explicit "quit" button inside the Kelp GUI window

[nikhilsaraf]

Desired Behavior

It needs to be more intuitive about how to quit kelp. We need some way of quitting kelp from within the app window.

Impact

Users will know how to close the app. This will also have the effect of shutting down all the bots before closing.

Feature Suggestion

Currently, users do not know to quit the app by clicking on the status bar icon.

Crossing out the window is disabled because electron does not give us a onClose() hook last I checked.

We can achieve the desired behavior by:

1. including a button inside the Kelp GUI (not via react but via the electron framework) which invokes the quit() method that we already have.
2. this will shut down all bots before quitting.
3. provide UI feedback that bots are being shut down to provide UI feedback on the user's click and to report progress.
