patch, 7 parts[DRAFT 2] StGIT, remotes, and parent information

Here is a new draft version, which re-implements stgit.config to call git-repo-config (without any caching to get things working right now), and with write support.

The 5 other patches were modified accordingly, so in this state we can see:

stgit$ ./stg branch -c bar origin Checking for changes in the working directory... done Recording "refs/heads/origin" as parent branch. Using "origin" remote to pull parent from. Branch "bar" created. stgit$ git-repo-config --get-regexp 'branch\.bar\..*' branch.bar.merge refs/heads/origin branch.bar.remote origin

There are many rough edges when you shake it, but that should give the idea.

Best regards,
