[Geary] some issues with windows

[Federico Bruni <fede inventati org>]

Hi all

I have a couple of issues with geary:

1. Window tiling is not working anymore: I can only maximize/minimize, I cannot move the window to left/right. I reported the same problem for evince here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=772942

Note: this happens only with the main window, while the (detached) message windows work fine.

2. In the accounts dialog, the window of a non-gmail account is too big and doesn't fit the screen, so I cannot save my changes and I must close the window with Alt + F4.

I had a similar problem with another gtk application (gnome software update) some time ago.
