Why does the same branch (trunk) take different backgrounds?

 An experimental change to implement this is on the server. Add the "brbg" 
query parameter to the timeline method to have the background color set by 
branch name. Add "ubg" to have the background color set by user name. Examples:

http://www.fossil-scm.org/fossil/timeline?n=200&y=ci&ubg 

 I tried Ross's proposed color choosing algorithm but it didn't work out. So 
instead I used the hash to select a Hue in an HSV color space, held the S and V 
fixed, and mapped the result into RGB. The color chooser code is here, if you 
are interested:

 Feedback is encouraged. Remember this changes is experimental and might 
disappear at any moment!
