[PATCH 2/4] git-svn: use commiturl in preference to url when constructing dst for branch/tag

[Igor Mironov <igor.a.mironov@gmail.com>]

When constructing a destination URL, use the property 'commiturl' if it is specified in the configuration file; otherwise take 'url' as usual.  This accommodates the scenario where a user only wants to involve the writable repository in operations performing a commit and defaults everything else to a read-only URL.
