Contact list rework

Okay, i've been doing this rework for quite some time and i think it's stable enough to be merged to make it some testing and feedback.

So how it looks:

Contacts are sorted based on their status and case of equality alphanumerically. Groups are placed to the end. I used mrlib/aligned-pasteboard as basis for new smart-list component.

When contact list has focus contact entries can be browsed via up/down buttons and selected with space.

Since this is a HUGE pull request please give it some testing, although it workes on my machine (C).
I suppose the more elegant version would be better, just in case it does change in the core. It'd be better to have it now rather than need it later. I think I'm ready to merge this into Master and apply some wrapper changes. Is there anything else you think should be done before the merge?
