NEW: net/purple-hangouts

Hi ports --

Attached is a new port, net/purple-hangouts. purple-hangouts is a Google
Hangouts plugin for libpurple.

---
pkg/DESCR:
purple-hangouts is a replacement prpl for Hangouts in Pidgin/libpurple
to support the proprietary protocol that Google uses for its Hangouts
service. So far it supports all the fun things that aren't part of the
XMPP interface, such as Group Chats, synchronised history between
devices and SMS support via Google Voice.

Only lightly tested on amd64, but all appears OK.

OK?
