[Adium-devl] Some AIAccount improvements

[Colin Barrett]

If either of these are already implemented, feel free to smack me ;)  
Just wanted to get some review on these before going ahead on this.

- It would be nice to know if sending an autoreply is supported  
natively by the service, mostly so the autoreply plugin can append  
(Autoreply) or some other flag on MSN or other protocols that don't  
natively support autoreplies.

- It would also be nice to know if a protocol generally handles  
actions (/me) at the protocol level. We'll need this when/if we do  
IRC, and on GTalk it would be nice to implement this, since the  
official client handles /me's. There may or may not be a XEP for this,  
but we'll still need to have a way to expose this property to the /me  
plugin.

Thoughts? I'm definitely up for implementing this on trunk.
