A mutt patch for a more colorful index

This patch enables different colorings for different parts of the index display. For example you can choose one color for the subject, another one for the author, and a third one for the flags.

Screenshots:

• Screenshot #1: Just a random screenshot...
• Screenshot #2: Notice how messages written by me are differently colored then those from other authors. This is done using indexcolor's author pattern matching.
