WiP: auto connect to ponyd service published via bonjour

Simple proof of concept.
Try next bonjour service if current one is removed or failed resolution
Added possibility to connect only to a specified Bonjour service name
Register ponyd as a bonjour service
Follow the existing code style
Stop bonjour browser and current service when calling `disconnect`
Added note in the readme about the autoConnect feature
Reset the delegate of the current bonjour service when necessary
Coding style, removed some tabs that were left
Removed unneeded NSNumericSearch and reformatted code
Connect to a specific ponyd server by default
Use the ioloop instead of creating a thread
thread import is not needed anymore
Fix swizzling mistake in exchangeSubviewAtIndex:withSubviewAtIndex:

other issues.
