[patch] Make git-svn init accept a target dir

Since I'm lazy I just hacked a bit git-svn in order to create a target
dir and init it if is passed as second parameter.

git-svn init url://to/the/repo local-repo

will create the local-repo dir if doesn't exist yet and populate it as
expected.

Maybe someone else could find it useful
