Release 0.4.6

=============



Enhancements

~~~~~~~~~~~~



* Add connection handle to GATT callback parameters. This paves the way for

  applications requiring multiple concurrent connections: read/write/HVX

  callbacks will be able to distinguish between peripherals by comparing per-

  device connection handles.



* nRFGattClient: move the allocation of the singleton to within the

  getInstance() method. This saves memory when nRFGattClient isn't

  instantiated.



* Disable GattClient features when using S110 SoftDevice. This is controlled

  by the pre-processor macros: MCU_NORDIC_16K_S110 or MCU_NORDIC_16K_S110.
