Create script printing controller name based on URL

Summary:
With this script, I am able to add bookmarklet to my browser which edits the
controller responsible for displaying current page by a single click.
Plus it can be useful also for other uses.

Test Plan:
  ./aphrontpath.php /
  ./aphrontpath.php D123
  ./aphrontpath.php /D123
  ./aphrontpath.php /D123/ # doesn't exist
  ./aphrontpath.php https://secure.phabricator.com/D123
  ./aphrontpath.php https://secure.phabricator.com/D123?x=2
  ./aphrontpath.php https://secure.phabricator.com/D123#comment-1
  ./aphrontpath.php differential
  ./aphrontpath.php /differential/
  ./aphrontpath.php /w/ # rewritten by custom config
