Add support for tweaking production/development output

[DannyBen]

cc #576, #575

This PR adds these options to the settings:

# allowed values: always, never, production, development
enable_header_comment: always
enable_bash3_bouncer: always
enable_view_markers: development
enable_inspect_args: development
enable_deps_array: always
enable_env_var_names_array: always

This allows the user to define which of these features is rendered in which environment.

@EmilyGraceSeville7cf - made some additions to settings.json schema, if you can review.

@DannyBen, I will review it in several hours.😀 I have checked linked issues and I can say for sure that I love this idea of having such settings added.

@EmilyGraceSeville7cf - note that I have just made the settings.json schema generate from YAML (in support/schemas folder), like we did with schemas/bashly.yml. It renders with 2 spaces instead of 4, this is why when viewing the diff without "Hide whitespaces", it looks like it was all changed.

LGTM 😄
