Only the repository containing the project root was known, so nested clones and
submodules (or a folder of side-by-side service repositories) showed no changes and
could not be committed or pushed. The project now has IDEA's VCS roots: the enclosing
repository plus those found below the project (scanned in the background, rescanned when
a .git appears or goes). Status covers all of them; path-based commands go to the file's
repository and repository-scoped ones take the selected repository.
The Commit view groups changes by repository and commits each one with included changes;
the branch widget names the selected repository and switches between them; Update Project
and Fetch run in every repository; Push lists every repository with outgoing commits; a
repository that stops in a merge or rebase is selected so Continue / Abort act on it.
Closes#12
