[aur-general] deleting phun* from aur

Just so people know, I will delete phun, phun4-32bit, and phun4-64bit from the aur because of http://www.algodoo.com/wiki/Phun "Phun was the open beta testing version of Algodoo and as such Phun is no longer promoted, developed or supported." Basically, it has moved to algodoo.
