plasma kpart theming

[Marco Martin]

Hey all,
today i hacked a bit around graphical styling of the Plasma kpart, that 
includes making svgs and fixing the newspaper containment/kpart code where 
needed (as result newspaper sucks a bit less on the desktop, yay ;))...

here it is:

the style (there are still some glitches, is to polish it up) is in 
playground, the patches are committed just in part.

The rationale is that the application dashboard for sure shouldn't look like a 
desktop at all (that is how would look definitely more dirty and more 
confising)

it rather should look like a document with quick recap info.
so yes, in that screenshot it looks like a friggin' website and that's exactly 
the intent ;)

some important points:
* the background is the same as the konqueror/kmail/etc "start page", *not* 
configurable (i think the plasma theme graphic used there would make more 
sense in those pages as well compared to the current old broken desktop theme)
* the plasma theme has at the moment exactly 2 elements and uses where 
possible native widgets (the backgrounds will also use native colors with the 
new stylesheet support in Svg)
* the newspaper has a big background for all applets (that is the main thing 
that makes it a "document" rater than "crome": that iage is not available in 
the default theme, so it will continue to -not- be there in an "usual" case

now, apart from feedback from artsy people, my greatest concerns is the usage 
if soo big pixmaps (the wallpaper and the big newspaper svg background) that 
makes quite a memory usage, but i think from the final look it's worth it.

Cheers,
Marco Martin
