Subject: Add `code-review`, subcommand runner

This script takes a subcommand as the first argument and executes an
executable called "code-review-${subcommand}", similar to the way Git
does subcommands.

Using this subcommand system, I can have different unrelated subcommands
in separate files/scripts, making it easier to organise the code.
