gaim scriptlet for service-discovery-applet to handle presence

[pharon]

Here's a small script for handling service of type _presence._tcp using gaim. It will call gaim-remote and pass it the requested chat target.

It's still crude, for example it doesn't check if gaim is running, and if it is, whether a bonjour account is configured. This is all possible with gaim's dbus interface. I will try to update.

Assuming everything is setup it will open a chat window to talk to the target. I tested with gaim2-beta5 on both sides and bonjour accounts setup.
