scan_lib_location finds shCore.js in pupload docs directory

For some reason, the php library pupload (php file uploads) includes the file shCore.js in its docs/api/js folder. This means that when scanning, syntaxhighlighter chooses this directory instead of the syntaxhighlighter_3.0.83 directory. By removing the pupload/docs directory and visiting admin/reports/status, syntaxhighlighter is correctly found and implemented.

This isn't really a bug, but it may be a problem that has an alternative solution other than removing the pupload/docs directory, so I've added it as a feature request instead. Let me know if I can be of further assistance.
