Make commands able to call each other without repeating code, and without tight coupling

[Snailedlt]

Description

It would be neat if we could call other commands from within a command. For example, if someone calls the -handler command without an argument, it would be nice if the -help handler command was returned.

Ideas

I think we can use the Strategy Design Pattern, and make a strategy for each command. That way it get's decoupled from the command itself, making it less dependent on it, thus making it easier to call from other contexts.

Possible dependencies

• TypeScript: We may need to add TypeScript for this to work as intended.
