Golang binding for Avahi announce

[Alexander Pevzner]

Hi Adam,

as far as I understand, if you perform lookup with the 
AVAHI_LOOKUP_USE_WIDE_AREA flag (which maps to LookupUseWideArea in my 
library), Avahi will use a "classical" unicast DNS instead of the mDNS.

So seems that everything is already in place and no additional effort is 
required.
