Add BridgeDB to Transifex

We need to add BridgeDB to Transifex. The .pot file is here: https://gitweb.torproject.org/bridgedb.git/blob_plain/HEAD:/i18n/templates/bridgedb.pot

For this to happen, I need commit access to https://gitweb.torproject.org/bridgedb.git/blob_plain/HEAD:/i18n/.

Christian wrote the following in an email to tor-assistants:

"I think currently only Nick has commit access to the official BridgeDB repository. But poking Sebastian to create a runa/bridgedb.git for you that Nick then can pull from maybe is the way to go."
