Title: Added link colors to the tree

just like 2.4 had, added colors for new/modified/deleted tree links to improve usability. The new flags that appear at the end of the links are generally hidden unless the div is scrolled - especially for long titles.
Colors are probably not the same as they used to be, but you can adjust them.
PS Apologies for the !important but I see they are used elsewhere in the file...
