removed the definition of defaultRGBFiles from the examples: it is now
hosted in the library.
removed function parseColors from examples. this is done during initPixmap.
added wmdocklib.defaultRGBFileList
removed wmdocklib.setColor (superseded by wmdocklib.initPixmap)
extended wmdocklib.initPixmap:
basic 16 colour palette [basic_colours] from rgb.txt (not hard coded)
alter_palette to (re)define an indexed colour in the xpm.
bg/fg can be a single character or a number [0..15]
' ' as transparent colour.
some debugging 'if 0:' code.
extended wmdocklib.getColorCode:
it reads either the given rgb file or the first accessible file from
defaultRGBFileList
corrected url in setup.py: it used to point to ibo!
