Trello Plugin

[LFDM]

Hey @hagenburger, made some baby steps for a Trello integration - I was the guy talking to you about this last week on the VimBerlin meetup, if you remember this ;)

I was kinda looking for a dual approach here - making this a stand-alone gem, that then also integrates with git-start. Was probably a bad idea though, not sure, we'll see how it goes. Might scrap the stand-alone part altogether, but still keep it as own gem to encapsulate this functionality better.

Will continue working on this whenever there's some time left, you can follow it on https://github.com/LFDM/trello_github, if you're interested. Code is still a bit all over the place, but it will come around.
