Refactor wxBitmapButtonXmlHandler before using wxBitmapBundle

Browse Source 
This replaces 4 calls to GetBitmap() with a single one.

Note that we now use SetBitmapPressed() and SetBitmapCurrent(), which
take wxBitmapBundle, instead of deprecated SetBitmapSelected() and
SetBitmapFocus(), which do not.

We also search for the parameter node only once instead of doing it
twice in a row if it was found, so the new code is slightly more
efficient.
