[OpenVerse] Bug in user cancel of a room download

[Ed Lange <elange@mediasoft.net>]

It looks like the new code prevents you from changing rooms if you have a
room download in progress.  But, if you click on that download and then
click "End Download", you can no longer change rooms at all.  The following
patch fixes this by changing "proc endDCC".  It could probably be done
better; I haven't checked to see if a failed room download causes the same
condition.

cd /usr/lib;patch -p0 <<EOF
