* 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.
