Upload names
------------

Patches LDM so that file uploads have names that resemble the original
name.

Install the xml as a standard vbulletin plugin.  One adjustable setting is provided:
if the plugin is active, it functions.

By default, LDM gives uploads a long random number as filename on the server.
This add-on gives filenames of the form <<nnnn-initfilename.type>> instead,
where nnnn is a 4-digit random number and <<initfilename.type>>
is the original filename, modified to remove characters other than
a-z A-Z 0-9 _-.
