- API change in WINGs for WMDraw*String().

WMDrawString() and WMDrawImageString() now take WMColor instead of GC as
  arguments. WMDrawImageString() receives 2 colors (text & background).
  This is to allow easy extension for Xft/Xrender and hide X low level details
- Added alpha channel to WMColor. 2 new functions also:
  WMCreateRGBAColor() and WMSetColorAlpha()
- Miscelaneous code cleanups in wtext.c
- Removed obsoleted acconfig.h and implemented its functionality using
  AC_DEFINE and AC_DEFINE_UNQUOTED as autoconf 2.5x recommends.
  This will definitely enforce the need to use autoconf 2.5x
