[development] New Core Theme for 5.0

[Anders]

I think I've seen some of this commented before, anyway:

* I would prefer it without the small icons. Especially the "posted"
one which feels pixelated and remembers me of Plone (we don't want
that...)

* I'm not sure about the centered forms, the headline on the User
login block feels misplaced. The post "Do poll bars have different
colors?" also looks weird because of the centering.

* I would push the search form at the top down a few pixels (or em's actually..)

* And I minor browser issue: the icons for the lists have incorrect
padding in Opera 9.01

A part from that I really like this theme. Great work.
