Allow hotkeys to be called on windows

[devn]

Note that this is tied to the feature request for the ability to create windows and not just tabs.

When a new window is created the ability to call a hotkey on the new window is very desirable. If you use SizeUp or another layout management application, being able to call a hotkey on individual terminal windows to put two stacked terminals on the left and one large terminal on the right, for instance, would be massively cool and functional. It is part of my "set up my terminal for this project" routine, and automating it would relieve a pretty ugly pain point I have when organizing my project workspace.

Any thoughts on this? I guess I'm just looking for a little hook that lets me say: after_window_creation(:hotkey => ["Command", "Shift", "X"]), or something like it.
