[Opensim-dev] HG friends and IM

[Diva Canto]

For those following the master branch, a heads up. I just pushed my 
recent work on friends and IM over the hypergrid. This brings a 
migration on the friends table (changed PrincipalID to a varchar(255)) 
and several configuration additions. If you want this new code to kick 
in, please check diffs on the .examples.

This shouldn't affect anything on non-hg worlds. If it does, ping me on 
the IRC.

Thanks,
Crista
