More work on the agent pools.
Lowered the default connection timeout delay as this really shouldn't
take longer than 3 seconds.
The log format has also been rewritten to make a more sane log.
Moved protocol tests to their own files.
Added call/queue and call/originate interfaces. Also a bit of
cleanup.
Changed the locate method to raise an exception instead of just
returning a None peer.
Removed temporary monolitic call test file.
Playground file.
