[PATCH 0 of 1] Configure branch color and width on graph

[Constantine Linnick]

graph: in hgrc specify line width and color of main branch

You can specify width and color to visually distinguish main branch (trunk) 
on hgweb's graph page. If color specified, all branch heads will share
same color. Settings format is branch.[color|width] = value, where width in px 
and color is six hexadecimal digits e.g.:
default.color = FF0000
default.width = 3
