xffm: dir colors

[Danny Milosavljevic]

Hi,

Hehe, I noticed that xffm can do colored files now :) Nice...

However, my theme makes all treeview backgrounds (nearly) black.
So normal files in the tree are kinda hard to read *grin*

Any chance to 
1) make the colors configurable (cfgfile, gtkrc) or 
2) check for base[] color of the tree and if it is darker than 50% in
average (r,g,b) then lighten all file colors up. 
?

I modified treeview.c in my version, so its ok for now...

Thanks :)

cheers,
   Danny
