[rabe-soft]

#660 / #659 fixes colorC.goh
The documentation (txt, html, md) still contains the old, incorrect declarations. This affects the following methods and typedefs:

new typedef struct ... ColorAndFlagReturn;
MSG_COLOR_SELECTOR_GET_COLOR
MSG_COLOR_SELECTOR_GET_FILLED_MONIKER
MSG_COLOR_SELECTOR_GET_UNFILLED_MONIKER
new typedef dword DrawMaskAndFlagAsDWord;
MSG_COLOR_SELECTOR_GET_DRAW_MASK
new typedef dword PatternAndFlagAsDWord;
MSG_COLOR_SELECTOR_GET_PATTERN
