Detect incorrect collision sequence files.

Changed the default collision sequence to 2 collisions. This makes it
easier to notice if the sequence file specified on the command line is
wrong.
Make it easier to change sequences.

The discrete delays and collisions target sequence files are now
defined at a higher level, allowing these helper batch files to be used
in more situations.
Allowing setting number of movements for targeted.

Note: This does not mean that one can specify a arbitrary number of
movements. The number of movements is appended to the file root
TargetedTargets. If the file with the corresponding name is not there,
this will fail.
Harmonize the end of task message.
Better organization of -sit, -deploy, -stow.
