rgb and cmyk versions in one document

- separate colors.tex, to include from any sub-document
- provide both rgb and cmyk versions
- use rgb by default, \def\colormodel{cmyk} for clean print version
- make timetable.sty work with all color specifications:
- new \defineeventcolors accepts 5 arguments: name, bg colorformat, bg color values, fg format, fg values
- new \leteventcolors accepts 3 arguments: name, name of previously defined color for bg, name of color for fg

ESE 21 red CMYK version very VAGUELY approximated by a non-professional
