Fix a bug in manual mode.

In manual mode, turning stations on caused an error. It was due to sid+1
being interpreted as a string rather thatn a numeric operation.
Minor comment edits.
Add rain sensor functionality for Bo.

Add a function (check_rain()) and pin definitions to enable rain sensor
capability for the Beagle Bone Black version of OpenSprinkler. A pin
definition for the relay is also included.
