webapp: Support using git-annex on a remote server, which was installed from the standalone tarball or OSX app, and so does not have git-annex in PATH (and may also not have git or rsync in PATH).

* webapp: Support using git-annex on a remote server, which was installed
  from the standalone tarball or OSX app, and so does not have
  git-annex in PATH (and may also not have git or rsync in PATH).
* standalone tarball, OSX app: Install a ~/.ssh/git-annex-wrapper, which
  can be used to run git-annex, git, rsync, etc.
