Cole Robinson 1d17b98852 engine: Move most remaining window tracking to UI classes
Kind of a big mess but it was difficult to untangle piecemeal.
Basically this drops nearly all the centralized window tracking
in engine.py and moves it to each UI class. If manager.py wants
to open a details window it does it directly, and vmmDetails tracks
the window object list itself. This simplifies things and makes
the code easier to follow.

There's still some weirdness with vmmConnect and connection callbacks,
but future patches will break those apart.
