merge completed - feature/GEODE-77 -> develop

[Bruce Schuchardt]

The feature/GEODE-77 branch is now dead.  I'll delete it in a few days 
if we're satisfied with the merge.

Thank you to everyone who helped with this project or helped offload 
work from people focusing on it.  That includes quite a few of you who 
are reading this!

I want to remind everyone that there is now no multicast discovery in 
GEODE.  You must now use a Locator service as part of your distributed 
system.  Multicast communications can still be used by setting a 
multicast port and address, but multicast is no longer an option for 
startup "discovery".
