[arch-dev-public] [signoff] licenses update

Just an addition of two new licenses. Signoff should be super-easy- make sure you have a plentiful supply of licenses in /usr/share/licenses/common/. PSF, Python license- http://bugs.archlinux.org/task/9467 ZPL, Zope Public license- http://bugs.archlinux.org/task/8998 We have a few packages that use these, they may need to be updated to point to these guys. -Dan
