Review request for Plasma.


Changes
-------

* Changed as requested by aseigo.
* Added missing connect.
* Added compatibility with old dataengines.


Summary
-------

First of all: **This is a preview of the patch** I'm still working on it but I need some advices.
Picture Frame does 2 really bad things (when used with huge images):
* it loads huge images (in my case 4000x3000 pixels) into X11 pixmaps
* plasma is blocked while the image is scaled
As side effect also X11 freezes.

This patch solves both issues using threads.

I think that we should remove "smooth scaling" option from our configuration UI. what do you think?
