command line: added --frames, touched up
From: Carl Karsten <carl@personnelware.com>
1. Added command line option -f --frames for number of frames to grab
2. changed the default -f from 1000 to 70
3. show defaults in --help
4. added a Version, picked 1.3 as the current ver because I consider the
original to be 1.0 and at least 2 changes have been made.
