Web Remote Control for Amarok 1.4

This is very simple and not very fail-proof script, which, when enabled, starts small web-server on localhost:4775 with now playing information and very basic controls (volume up/down, next, previous, play/pause, stop, rating plus/minus). ® is for refreshing the page, but it automaticaly refreshes each 6 seconds.
Requirements: perl, perl module HTTP::Server::Simple

It doesn't depend on any input from amarok, so you can run it just by starting the script. Another possibility is to create folder ~/.kde/share/apps/amarok/scripts/matrixx-web and there the file matrixx-web.pl (don't forget to add +x permissions) and the specs-file (all the way down). You can rename matrixx-web to whatever else, but you have to do it everywhere (folder and both file names).

For trinity: i think the folder name will be ~/.trinity/share/apps/amarok/scripts/matrixx-web - everything else should be the same.
