Commit message:

Release 0.1.0
=============

We've achieved significant gains in power consumption: the BLE_Beacon demo now
runs at around 35uA of average current broadcasting once a second at 0dB; when
not using the radio, this demo consumes around 7uA.

Features
~~~~~~~~

- Replace initialization of high-frequency external crystal clock-source with
the use of low-frequency clock. This brings in significant gains in power
consumption.

- Re-implement the micro-second timer on nRF51 using the app_timer module
(which internally uses RTC). This limits the precision of the us_Timer to
30uS; but brings in significant gains in power consumption.

- Reduce the number of available app_timers and the event depths for app-timer
events; this will reduce memory consumption for zero-initialized data by
around 1K.i

- Remove the call to conn_params_init() at startup. This is not mandatory; and
was causing an unnecessary re-negotiation of connection parameters a few
seconds into every connection.

- Reduce default transmission power level to 0dbB (was 4dbB before).

- Reduce min connection interval to 50ms and max to 500ms (previous values
were much larger).

- Replace a few instances of use of wait() with nrf_delay_us().

- onConnection() callback now receives connection-parameters applicable to the
new connection.

- onDataSent() callback now receives a count parameter containing the number of
times notifications were sent out since the last callback.

- A 'reason' parameter has been added to Gap::disconnect() to indicate the
reason for disconnection; and also to the onDisconnection callback to
receive a reason from the remote host.

- disable the app_gpiote module by default.

Bugfixes
~~~~~~~~

- onDataWritten() callback now passes an additional parameter
(GattServer::WriteEventCallback_t) encapsulating the update. This avoids
having to re-fetch the updated characteristic's value attribute. It also
fixes a bug where multiple updates to the characteristic's value-attribute
could get clobbered if they occurred in quick succession before the
callbacks could be processed.


Compatibility
~~~~~~~~~~~~~

Compatible with revision 0.1.0 of the BLE_API.
