Feature-request: add additional path to sizeItDown method in fullscreen module

[guest]

The current implementation of the sizeItDown method in the fullscreen module calls the Xinha.initSize() method to go back to 'normal' dimensions. In my usecase the editor's size/resizing is controlled by a Xinha plugin that is connected to a clientside layout manager which uses the YUI library to provide a dynamic page layout. The initSize() method will do it's job correct if there is no resizing during fullscreen, but if fails to get the correct dimensions if there is.

For this I've written a patch that adds a 'restore' path to the sizeItDown method; before the editor goes into fullscreen, the editor's dimensions are stored in the fullscreen module. When we return from fullscreen, the previous dimensions are restored adding/substracting the difference between the current and the previous viewport.

The path is configured by property Xinha.config.fullScreenSizeDownMethod with default value 'initSize' and optional value 'restore'.
