Better service icon support (google apps)

I use Google Apps extensively and have many contacts that do as well - Digsby works great with these accounts (just like native gmail addresses in Google Talk) but the service icons for these are rather generic lightbulb icons.

I realize other people use the Jabber protocol and maybe this is the default icon for that? But it would be lovely if the contact is using a google server if they could have the google talk icon, even if they are on google apps (non-gmail domain).

Perhaps look for the prefix "gmail" or "Talk" in the resource string?

That's easy enough.  We already check the resource to do a cheap test to see if the remote client is capable of file transfer with us.

While this piece is easy and cheap, I'll have to take care of an issue with merged contacts (which depend on the service used) before this is 100%.
