Trim Whitespaces in Debug Config Parameter

Pounding my head against the wall trying to figure out why 'debug: insteon:4, json' wouldn't work. (Turns out debugging was enabled for ' json', very annoying).

This trims all leading and trailing whitespaces around the parameters.  It also trims any white space between the ":" allowing for example 'insteon : 4'.

Much more user friendly.
