Jira 836, Enumerate non connectable Peripherals in Central scan …

Added feature:
  - In Central mode, the BLE library should enumerate Peripheral
    that are non-connectable (eg beacon).

Code Mods:
1. BLEDevice.cpp:
   - Add the call to get Manufacturer Data info from a
     Peripheral.  Non-connectable device may only broadcast
     this info.
2. BLEDevice.h:
   - Prototyping.
3. BLEDeviceManager.cpp:
   - Delete the filter about non-connectable advertisement.
   - Added APIs, hasManufacturerData(), setManufacturerData(),
     hasManufacturerData(), to gain access to adv info
     of non-connectable Peripherals.
