update
Updated (working) initial tests with docker.io.
Added stats
Need generators support from CS.
Moving to bluebird, might try co.
Corrected typo.
Moved to using bluebird promises.

Apparently I can't test over 30cps on my laptop using docker.io.
This will be a brand-new version.
errors as events in most cases
Drive two servers.
Updated termination tests.
`@once` returns a Promise.
Added `@on` to be able to monitor `error` events.
Added a simple test to validate the cps of plain FreeSwitch.

I can get FS inside docker.io at 28cps with two `esl` servers, while plain XML dialplan goes up to 30cps. Not bad.
Collect `@data` in case some commands do not return any body.
Clarified test layout, added LCR test.
Cleaned up logging during tests
`resolve` and `reject` should not be returned.
Removed cruft
Moved socket events query inside parser.
parser: new error reporting on socket
