Update copyright for 2013
Update debian copyright. ;-/
Merging in James Page's packaging tweaks for quantal.
Pass lintian. This is still annoyingly redundant. ;-(y
Ugh, it looks like lintian wants a duplication of the license in debian/copyright....
Debian copyright wants a real file, so change LICENSE to symlink.
Added Debian/Ubuntu packaging - thanks to James Page.
