Contour activity screen and plasmoids

[Marco Martin]

Hi all,
just a quick update on the Contour activity screen: it now supports layouting 
of plasmoids, and the result is quite good looking:

there are still some limitations, namely 
* there isn't a way to call the add widget dialog without right mouse button,
* no way to invoke the configure dialog 
* the close button is immediate, potentially dangerous (i would love to use 
the drag thing from appletstrip)
* is still possible to resize the boxes smaller than the minimum size of the 
applets, gotta be careful

all those issues should be pretty easy to fix, is already enough for showing a 
single plasmoid in desktop summit demos tough.

Cheers,
Marco Martin
