Logically parse TVRage's "shows on tonight" RSS feed. Allows you to define a list of shows to be displayed. Display format is as follows: TIME SHOWNAME EPISODE -- 10:00PM Elementary (03x19)

$showList = array

	'Supernatural',
	'Person of Interest',
	'Elementary',
	'The Five'

$timeOffset = -6; // in hours, can be negative.
