Make all actions honor the optional argument -g or --group

Browse Source 
This make it possible to append '-g' or '--groups' followed by
space separated group names to any CLI action command, and the
set of generated files affected by the command will be limited
to the selected groups ('examples', 'tutorial', and 'demos').
Default is all groups. A simple help text is added for each of
the arguments (action and groups) to improve the autogenerated
CLI help output.

This is a squash rebase of these commits:
- p ec29076 Make all actions honor the optional argument -generate
- s e3ad11a Move open_file_append() outside the if to avoid re-open
- s ba4b900 Avoid including readme in all file groups
- s 1ca8bd1 Simplify code
- s a9e7337 Rename some variables to better reflect their contents and relations
- s 58a54b2 Move test to include readme inside collect_filenames() function
- s f2a0db0 Improve status output by adding group name
- s d3b299b Rename -generate option to -g/--groups and add argument help
