Update pic12 executive to not boot apps on ALARM

You can now force all of the mib modules to not start
running user code if ALARM is low on reset.
Remove potential bug with analog pins.

You should always set a pin level using LATXY, not RXY.
Internally the cpu does a read-modify-write operation and
analog pins are read as 0, so if you touch RXY, you can
unintentionaly reset all the analog pins to drive 0s.  LATX
if the register holding the output values, RX is the register
holding the currently measured values.
Fix bus in bus_reset code.

The bus reset line is high for cutting the bus off, not low.
Add power on rpc call
