Support multiple branches / project versions #119
Description
Right now Traduttore supports only translatable strings found in the master / default branch of a repository.
What if you have two branches in your source code repository, e.g. master and production, with both having different translatable strings?
What if you build an open source plugins where translatable strings can differ with each version (i.e. tagged release)?
I wonder if and how we can support such use cases.
