git-svn: Allow certain refs to be ignored

Implement a new --ignore-refs option which specifies a regex of refs
to ignore while importing svn history.

This is a useful supplement to the --ignore-paths option, as that
option only operates on the contents of branches and tags, not the
branches and tags themselves.
