updateDisplay.sh

More involved script for updating SPC Tools. This includes some very user/system based items, so unless you are doing work just like I do, there is stuff in here you don't need.

Highlights

• It computes all of the images before moving them, which makes loading from a slow internet connection more stable
• Command line argument lets you specific subdirectories from /data/
• If more than one version is running, it will provide a warning. Two copies writing to the same directory can cause lots of confusion
• The system will run for 12 hours and then quit. It keeps this program from running in the background forever.
