New topic: distribution

I'd add a new section listing the biggest and most influential projects that already moved to GIT. This could be categorized by programming language or community:

Java:
- eclipse
- apache software foundation (planned)

C(++):
- KDE, QT
- Gnome
- X.org, freedesktop

The text should give a link to the full list: https://git.wiki.kernel.org/index.php/GitProjects
