Added a delay method on Scout to allow the system to continue performing system tasks

Added Scout.delay() - this will handle when the millis rolls over (~
every 52 days of hardware uptime)
Updated the examples to use this feature.  Also updated the BlinkRGB to
show using specified blink delay values and using the default (500ms)
