This convenient method allows to expand all children of the item
recursively.
This is directly supported by both native implementations, so it makes
sense to have this in wxDataViewCtrl itself, even if it could be also
(less efficiently) implemented in the user code.
This code doesn't work (and probably doesn't compile) anyhow, but at
least try to do the right thing in it and override DoExpand() instead of
adding a virtual Expand() hiding the non-virtual version in the base
class.
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.
