Add VBT based on error bits for RollerShutter and Relay

[klew]

For RS we have defined value flags:
#define RS_VALUE_FLAG_CALIBRATION_FAILED 0x2
#define RS_VALUE_FLAG_CALIBRATION_LOST 0x4
#define RS_VALUE_FLAG_MOTOR_PROBLEM 0x8
#define RS_VALUE_FLAG_CALIBRATION_IN_PROGRESS 0x10

For Relays:
#define SUPLA_RELAY_FLAG_OVERCURRENT_RELAY_OFF 0x1

RS and Relay channels should have Reactions for above values/errors/states.
