v3.0.t7

-added a dely to DetectLoop after a positive motion detection to
 prevent motion event overlap.

-moved the 2 image diff pair compair to proper "end of array" in
 DetectLoop.

-increased the size of the image stream so queded up events will
 be able generate thumbnails properly.

-cleaned off a bunch of unused parameters in the code.

-adjusted the default motion sensitivity after real world
 testing.

-added libfuse-dev to setup.sh since imagemagic needs that to
 operate.
