Add JGit talk

The Gerrit community expressed the wish to be closer aligned with the
JGit community, hence the community managers tried to organize a JGit
talk at one of our user summits. I talked with Ivan Frade (Google) about
this and I'm glad that he is willing to do a JGit talk at this year's
user summit in Sunnyvale. The concrete topic of the talk is still being
discussed but we already want to secure a slot for this talk. Ivan's
preferred day for this talk is Saturday, so I'm taking a slot there.

Details about the talk will be filled in once the topic is decided.
