[Bug-librejs] Recognise Unlicense using LibreJS

[adam plaice]

The unlicense:
http://unlicense.org/UNLICENSE
while not recommended by the FSF, is a valid, GPL-compatible free software license (http://www.gnu.org/licenses/license-list.html#Unlicense), but it is not recognised by LibreJS (and is not listed in /lib/js_checker/license_definitions.js in its source). Would it be possible to add it?

I understand that you may not want to encourage people to use it, but if an external script one wants to include is licensed under it, one doesn't have much choice.
