initial commit for getting gateway to ping hub instead, also use new connection statistics message
using ttl instead of time. Need redis 2.6 for time, and precise default is at 2.2
fixed typo
fixed variable references
fixed problems with ping
merged with upstream
adding local and remote clients for concert debugging (WH)
more updates to tests to use concert. I should probably put concert test giles in a separate package.
auto invite clients for now
Merge pull request #221 from piyushk/ping_from_gateway
