kickoff qml

[Marco Martin]

Hi all,
one thing i would like to have merged for 4.10 is the qml port of kickoff.
i have been looking at it past few days, and it seems to have most of the 
features, even tough is still quite rough, i'm not 100% sure it may be ready 
yet.
i've fixed some things in last couple of days, it still has some layout and 
painting problems (sometimes elements don't seem to repaint correctly)
right now even if not really far i don't think is really merge-able yet.

also the code organization doesn't seem to be that great (it has a quite 
complex logic and there is a context menu copy in each delegate that makes 
things quite heavy)

i think it should have a minor refactor on how the various pages are managed, 
a qml file for each page (favourites, applications, leave etc) and one single 
contextmenu for each page.

I would like to invite people to test it (kickoff-qml branch) to see if it can 
be made good enough in time.

Cheers,
Marco Martin
