New Git repositories start out without any branches, but the HEAD
reference points to "master" by default. This means that the first
commit will create a master branch.
This change adds a HEAD file to the Git template with a different ref.
This means that new repositories will commit to a "main" branch by
default instead.
The HEAD file is added to COPY_ALWAYS, because Git's HEAD must be a
regular file and not a symbolic link.
While trying out the approach outlined in Croaky's latest [blog post], I
realized that running `rcup` would not also pull updates from my local
extensions. If you clone your extensions as `dotfiles-local`, this
update will pick them up.
Non-existent directories are ignored by rcup, so it won't cause issues
if you don't have `dotfiles-local`.

The rcm suite is designed to replace the `./install.sh` script found in
this and many other dotfiles repos across GitHub. By using rcm users can
combine multiple dotfiles repos, tag dotfiles, have host-specific
dotfiles, and other powerful features.
This commit removes `install.sh`, updates the README, adds a post-up
hook that vundles the vim bundles, and adds a `rcrc` configuration that
ignores `README.md` and `LICENSE` and sets the dotfiles directory to
just `dotfiles`.
