Merge wxQT branch into the trunk.

This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.
