LibCore+Base: Add way to hide ArgsParser opt.s from specific usage texts

Browse source 
This adds the ability to hide certain options from certain help texts.
`--complete` is always hidden, whereas `--help` and `--version` are
hidden from Markdown help text only.
Note that in all cases these three options are hidden from the short
usage line.
