Subject: [PATCH] Add jsparse.php maintenance script to run given JavaScript
 files through JSMin+'s JS parser for syntax validity checks.

This also confirms JSMin+'s fairly abysmal memory usage on large complex files. :) Pass --memory-limit to set to arbitrary values to see where it dies on your file. ;)
