Create Button Interaction Framework

[andrewlalis]

Create a framework that allows us to handle a variety of button interactions cleanly.

Here are some use cases that must be addressed:

• One-off buttons that, when pressed, do some logic that might depend on parameters that were set when creating the button.
• General-purpose buttons that have a fixed function at all times.

I want to suggest a few things about this:

• bind the button/interaction framework to commands. Every interaction is assigned to a specific command (e.g. warning per button triggers a method ik the warn command). The interaction id could have the format commandname:whatever (and commandname:subcommandname:whatever if the command uses subcommands).
• Make the interaction framework independent of buttons allowing other interactions.
• Use a default-method in the command interface for triggering interaction messages. This would make commands work without interaction responses.
• Let the interaction action return a response just like the coommand action does so that the bot definitely responds (also include a response on thrown exceptions).
