Previously was always subtracting 12 hours from the set hour value (in H12 mode) this cause a bug if the set hour was <=12.
Now by default the interrupt is enabled but the mask is set to no compare.
This is not strictly required for a wake alarm as the IRQ routine will wake the board.
Now the identifiers from /component/rtc.h are used.

First commit fixes a bug in setHours() (if hours < 13 and in 12h mode).
The main additions add the ability to set an interrupt based alarm which can call a user specified callback. It will work in sleep mode and the alarm will wake the board. Alarm masking is implemented to create periodic alarms.
