Merge lp:~zeitgeist/plank/zeitgeist into lp:plank

[Rico Tzschichholz]

[Danielle Foré (danrabbit)]

I like the idea, but I'm worried about things just popping up unexpectedly. I think it might make sense to wait for the user to open one of the suggested apps and then "smart-pin" it at that time. In this way, we're not actually adding the item, we're just not removing it :p
