[Feature] Add acces to repo through file system.

[TrevCan]

I have an app that can clone Git repositories much better. It is called Working Copy. It even exposes the repositories on the iOS File System. I think it would be more convenient for some if the PassForiOS app could allow reading a repository inside the iOS File system.

I'm unsure if the app would be able to write to the same directory but I would be fine with just reading it and writing it to another directory if that were the only option.
