Add support to the capture script for properties that control the script execution. Script properties are specified in the 'properties' section before the actual list of controls specified in the 'frames' section. Define a first 'loop' property that allows repeating the frame list periodically. All the frame ids in the 'frames' section shall be smaller than the loop control. Modify the capture script example to show usage of the 'loop' property and better document the frames list while at it.
