This reverts commit 59e92d58.

Readme updated to reflect that Trigger support is now included and a patch is no longer needed

Reduce dependency stack of rewrite map script to prevent hangs

Ensure every value in the $sites array is a genuine site dir and not an alias.
For the real dir c, this changes ($sites['a']='b'; $sites['b']='c';)
to ($sites['a']='c'; $sites['b']='c';) to ensure continued operation if alias b is deleted.

This moves the logic for cache misses to a separate script,
rewrite_miss.php, which will process the rewrite and return
the correct route. The rewrite_miss.php script includes a
time limit to prevent hang-ups from occurring.
