Add missing licenses
Clarify that we're talking about GPLv2; also, fix address in LGPL license statement in debian/copyright -- the FSF moved a _long_ time ago...
Update FSF address in individual files, too
Add missing numbers (whoops)
Catch all address changes

grep -rl 'Temple Place' turned up a number of different spellings for
what was essentially the same address, which my first sed line didn't
catch. Also, there are more files than just the .cpp and .h ones which
contain the old FSF address.

This adds all the missing files (and there are plenty of them...)
