    layerindex/tools/import_project.py: Detect remote name & branch

    Don't assume remote name is origin, run `git remote` to get the remote
    name.  When checking the remote, detect the branch as well, that way the
    layerindex will work if the remote branch name and local branch name do
    not match.

    Note that this currently only supports one remote.
