#855 hotkey for toggeling max vert./horiz. size

[Jens Elkner]

It would be very useful to be able to use a hotkey to toggle the max. vertical and horizontal size of iTerm.

E.g. cmd+H sets x position of the term to 0 and its width to the size of the current screen but leaves its y position and height as is.
Analog for cmd+V: sets y position of the term to 20 and its width to the height-20 of the current screen but leaves its x position and width as is.
Pressing the same key combination again, should restore the old position and width/heigth.

Actually I'm really missing such a feature - on normal *ix it is provides by the Window Manager for more than 15 years ...
