Overview of changes:
* Properly filter subcommands on listing
In contexts like main --help and tab completion, Saturnin would show
also arbitrary files from libexec that did not start with dedicated
prefix ($SATURNIN_LIBEXEC_PREFIX). This was a mistake and was never
intended to work that way.
* Hook code is now run as separate bash process
Running it within sub-command code was a little bit too unsafe;
there's no need to be evil^Weval here.
* Rewrote saturnin__version() (used for app --version)
Newly, --version will only incorporate tagline if it was defined in
mkit.ini.
Also "Powered by Saturnin" line has been added so that we don't have
to ask user every time.
* Added --saturnin-get-saturnin-version
It's a good idea to include this with test reports and the like so
we're making it more accessible to scripts.
* API documentation clarifications
* Codebase maintenance
* Refactoring for code readability
