resolves #112 Restart sleep if WDT not what awakened CPU. #113

A volatile flag is set in the WDT ISR to show that the WDT interrupt happened. The flag is cleared in functions when not SLEEP_FOREVER before the interrupt is enabled. When an interrupt awakens the CPU, the flag is checked and the CPU put back to sleep if the WDT interrupt was not the cause of the awakening. For the case of SLEEP_FOREVER, the flag is set to "true" before the CPU is slept, and the functions return when awakened by any interrupt.

Apologies for the white-space variances.

I suggest that the sources be consistent on white-space policy. The current sources have both tab and space on the same line.
