The objective of this patch is to replace the old
default theme to a new one inspired by the released
For now the goal is not to replace all the templates
yet, just to take care of the main page tpl and styling.
I'll try to respect the theme appearance as much as
possible, but for this 1st patch BC will be favored
(we'll see about fancyness later on, first we'll try to
get something that display well with old browsers
