Internal work - Draft phase framework for Franken

FrankenDraft currently is just the card drafting portion, but needs to expand to allow map building and faction building, as well as more improved setup features. It would keep things more manageable to move lots of logic out of FrankenDraftHelper and into a state-machine-like system where the draft is represented by a series of draft phases. Each phase would be responsible for handling the logic for that particular phase (setup, draft, map, faction build). Ideally the system would be portable to allow future bag draft variants (like Mantis draft).
