implemented variable to enable/disable printing. Cleaned up some code, removing old commented stuff.
Removed wait_for_edge button presss interrupt. That caused segmentation faults in the GPIO library. Function now returns true/false if button is pressed or not
added collage variables and collage detection at beginning of script. Updated displayEntertainment for use with collage variables and better logic to handle multiple collage files
changed ink level checking command to use 'sudo.' this might have been uneccessary as I think the USB printer was faulting when ink level checking was broadcasting it wasn't working
Added some collage variables and cleaned up the script a bit.
