MAJOR REVISION

Revised thinking on API of this class:

* Removed support for NSNotifications; instead rely on CBCentralManagerDelegate

Renamed shouldPingRSSI to willPingRSSI.
Removed call to persistPeripherals upon exit. Not necessary anymore.
Refactor handleFoundPeripheral: so that it only deals with discovery.
