Several changes to resising windows and layout widgets. This commit still has some bugs. Moved the implementable widgets from mde.gui.widget.Widget to miscWidgets, leaving base widgets in Widget. Rewrote some of GridLayoutWidget's implementation. Made many operations general to work for either columns or rows. Some optimisations were intended but ended up being removed due to problems. Allowed layout's to resize from either direction (only with window resizes). committer: Diggory Hardy <diggory.hardy@gmail.com>
