kdepim-4.4.x for f15

[Rex Dieter]

Per our team meeting this week and after consulting upstream, the kde-sig 
decided kdepim-4.6 isn't ready yet and and to roll back to kdepim-4.4.x for 
fedora 15 (and ideally squeeze this in for the upcoming alpha release).

We'll continue to provide kdepim-4.6 in rawhide (targetting f16 now) and 
unofficial test builds in kde-unstable repo for further testing and 
feedback.
