Enforce start-capture guide deviation

Previously the start-capture guider-deviation check was not applied in the middle of a sequence, just on the first capture in a sequence.

This is the issue, now fixed. #213 (closed)

This also corrects a bug where the the captureDelayTimer in capture.cpp needed to configured as a SingleShot timer. Without that, suspended jobs would resume "poorly" in that the resumption might be in next sequence, or the final sequence.
