New Package: ruby-svn2git (#7979)

* New Package: svn2git

https://github.com/nirvdrum/svn2git

svn2git is a tiny utility for migrating projects from Subversion to Git while
keeping the trunk, branches and tags where they should be. It uses git-svn to
clone an svn repository and does some clean-up to make sure branches and tags
are imported in a meaningful way, and that the code checked into master ends up
being what's currently in your svn trunk rather than whichever svn branch your
last commit was in.

* Actually requires +perl variant of subversion.

* fix style issue.
