Support address types (#18) 

* nrf5/modules/ubluepy: Adding new enumeration of address types.

* nrf5/modules/ubluepy: Adding constants that can be used from micropython for public and random static address types.

* nrf5/modules/ubluepy: Adding support for optionally setting address type in Peripheral.connect(). Public address is used as default. Address types can be retrieved from 'constants'. Either constants.ADDR_TYPE_PUBLIC or constants.ADDR_TYPE_RANDOM_STATIC.

* nrf5/modules/ubluepy: Register central GAP event handler before issuing connect to a peripheral. Has to be done before connect() function as a connected event will be propergated upon successfull connection. The handler will set the connection handle which gets connect function out of the busy loop waiting for connection to succeed.

* nrf5/modules/ubluepy: Removing duplicate setting of GAP event handler in connect().
