Rewrite upload filename if not english or number letter

Sets uploaded media filename to lowercase as filter on sanitize_file_name. Based on post at Stack Overflow asking if there is a way to “Rename files during upload within WordPress 3.0 backend”.
Created for WordPress 3.0.1+ which saves any uploaded media filename (Image, Video, Audio) as lowercase. This effectively changes the name of the file at upload if a user were to upload a file with any uppercase characters.
For instance:
<ul>
<li>MOVIE-FILE.MOV > movie-file.mov</li>
<li>Movie-File.wmv > movie-file.wmv</li>
<li>ImAgEfILe.gif > imagefile.gif</li>
<li>imageFile.JPG > imagefile.jpg</li>
<li>ETC > etc</li>
</ul>
Note: WordPress sets file extension to lowercase. This plugin does a strtolower on the filename.
