Check short style URLs for filesystem conflicts

by default, g2 short urls have all a prefix.
e.g. all view (showitem) pages have a /v/ , all downloaditem requests have a /d/ prefix etc.

say you remove this prefix /v/ or /d/ in site admin -> rewrite -> rules.
now a url to album "people" would look like this http://example.com/gallery2/people .
say you create now an album with the name "themes".
the url would look like this http://example.com/gallery2/themes .
now we have a problem since in the gallery2/ folder, we already have a subfolder with the the name "themes" (same for /lib, /modules, ...).
so the webserver would point to the subfolder rather than to the album with the same name.

this is one of the conflicts that could arise. say you still had the /v/ prefix, then the URL would look like this: http://example.com/gallery2/v/themes and there wouldn't be any conflict (in this case).

addtionally, the maintenance task checks the flat URLs for conflicts (if you have the user contributed flat urls module installed).
