#108 UpLoad plugin to respect InterWikiMap entry

I changed the UpLoad.php plugin file to calculate the
appropriate upload directory from an Upload entry in the
InterWikiMap page.

Not yet tested thoroughly, but I guess it's a good
improvement.

Btw: I'm an M$ dummy, so I attached the whole file
instead of a diff :(

This is a good idea.
But I want to change the upload dir to be user-specific also.

Upload:MyUserName/uploaded-file.txt

Maybe we should add a %u to be expanded to the curretn
username in the interwiki map, similar to %s for the pagename.

That's still not correct for custom interwiki map's, but I
see what I can do. I'll also add %u and %d expansion
(username and date)
and mkdir the intermediate dirs.

Note that "Upload:" is automatically added to the interwiki
map at startup, so most of your logic is not needed.
