[Dovecot] PATCH: Advertise X-REFERENCES2

[Michael M. Slusarz]

Don't see any reason why X-REFERENCES2 should not be advertised in the  
CAPABILITY string - the wiki indicates this is a new addition for 1.2,  
and RFC 5256 explicitly states that the THREAD= is to be used for  
upwards-compatible extensions.
