Allow non-RGB colors in CSS

The -cha-ansi color type now sets ANSI colors in CSS.

Also, color correction etc. has been improved a bit:

* don't completely reset output state in processFormat for new colors
* defaultColor is now separated from ANSI color type 0
* bright ANSI colors are no longer replaced with bold + dark variant
* replaced ANSI color map to match xterm defaults
