Add Arithmetic commands for VAR 

New Arithmetic commands to be used with VARs:

ADD1 to ADD5: Add a value to VAR[x]
Usage: ADD1 15
Result: VAR1 = VAR1 + 15

SUB1 to SUB5: Substract a value from VAR[x]
Usage: SUB1 15
Result: VAR1 = VAR1 - 15

MULT1 to MULT5: Multiply a value to VAR[x]
Usage: MULT1 15
Result: VAR1 = VAR1 * 15

SCALE1 to SCALE5: Scale a value from a low and high limit to another low and high limit and store it in VAR[x] (directly equivalent to MAP arduino command)

Syntax: 
SCALEx value, fromLow, fromHigh, toLow, toHigh

Parameters
value: the number to scale

fromLow: the lower bound of the value’s current range

fromHigh: the upper bound of the value’s current range

toLow: the lower bound of the value’s target range

toHigh: the upper bound of the value’s target range

(omitted values are taken as zero)

Usage: SCALE1 15, 0, 100, 0, 1000
Result: VAR1 = 150
