git-rewrite-branch: touch up

 * change USAGE to not imply an order between `-h` `-v` and `--svn`
 * have panic() print to stderr, not stdout
 * use [[ $var == string ]] instead of [[ $var = string ]] for readability
   (the only place I used a single = was when checking argument numbers)
 * add "Usage:" comments to functions
 * move git-rewrite-branch--appendid into the main file, as a quoted string
