Added an EddystoneURLConfigService in addition to UriBeaconConfigService. Updated README and converted comments that used UriBeacon to EddystoneURL in the EddystoneService.h

Dependents:   mbed_EddystoneURL_Beacon_ssci mbed_EddystoneURL_Beacon_ssci mbed_EddystoneURL_Beacon_ssci

Fork of BLE_API by Bluetooth Low Energy

Revision:
797:13164356b568
Parent:
728:997ba5e7b3b6 
Updated EddystoneURLConfigService.h : 1) lockedState now is a member of params.lockedState ; zeros are not the unlock value (and a valid key), this now passes the Validator, 2) After disconnect the timeADV is disabled, and ADV params recreated.
