add magnet.protocol file so fatrat gets associated to magnet:/ protocol

[dwatzke]

it could look something like this I guess:

[Protocol] exec=fatrat "%u" protocol=magnet Icon=fatrat input=none output=none helper=true listing= reading=false writing=false makedir=false deleting=false URIMode=rawuri

[dwatzke]

please add this file for kde4, it makes life a bit less depressing...

also, for a non-DE-specific solution see: http://askubuntu.com/questions/108925/how-to-tell-chrome-what-to-do-with-a-magnet-link

Implemented the DE-agnostic approach.
