Allow labels for Redmine links
Allow wiki syntax like:
"some important ticket":#34 and "this big commit":r123
Added via attached patch (against r3308) (and at http://github.com/andyfowler/redmine/commit/bcc4dbca53629a61ea9551d62c6c6b7d8d44247f). I also sent a pull request to Eric Davis. Not sure what the best way was to submit this.
