[GSOC-UPDATE](02.08) Impress Remote

[Andrzej J. R. Hunt]

Hi everyone,

Today I implemented server discovery using multicast -- the client can 
now successfully find the address of at least one server (once I get a 
build working on my desktop I'll test that everything works when there 
are two servers on the network).

Since osl Sockets don't appear to support multicast, the latest code on 
the LO side involves plain C sockets, however it appears that the code 
should be platform independent if the correct headers are imported.

I intend to try to rebase on master tomorow to allow me to test whether 
that builds over the weekend (I want to do a full debug build as well). 
Just to make sure: is git merge the correct command to use? (Git rebase 
would mess up histories as far as I can tell?)

Cheers,

Andrzej
