[Part 3] Download torrent & newsserver packages

[koper89]

BTW, if I compiled my own rtorrent 0.9.4 in f.e. a package should I add those deb packages (i used checkinstall to generate them) Or in my script I should add whole compilation process? (It's at least few hours of work on RPi)

I'll try to update sickbeard and if couchpotato is also outdated I'll fix it also. And will try to add rtorrent package.
