Similarly to the previous commit, it doesn't seem to be worth it to
avoid including these simple and common headers from there and it
simplifies code and will allow making the converter functions inline.
Follow standard practice and include the header corresponding to the
source file from it explicitly.
Also include wx/gdicmn.h from the header itself, this is a pretty common
header and there is no real advantage in avoiding it there and including
it allows to avoid a bunch of forward declarations.
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.
