userdiff: add support for Fountain documents

Add support for Fountain, a plain text screenplay format. Git facilitates not just programming specifically, but creative writing in general, so it makes sense to also support other plain text documents besides source code. In the structure of a screenplay specifically, scenes are roughly analogous to functions, in the sense that it makes your job easier if you can see which ones were changed in a given range of patches. More information about the Fountain format can be found on its official website, at http://fountain.io .
