More Hooks D&D5e

Adds more hooks to the 5e system. This is intended to be a library module for other modules (or Hook Macro users) to leverage.

The API is going to follow Semantic Versioning as it is likely to undergo sizable changes as the hooks are hammered out.

LPT: Use CONFIG.debug.hooks = true or Developer Mode to more easily explore what a hook does and when it fires.

This library itself depends on lib-wrapper and socketlib, if you are depending on it, it's wise to add those to your dependencies as well so activation occurs correctly.
