Subject: Add a game phase to perform judging
X-Git-Url: https://git.cworth.org/git?p=empires-server;a=commitdiff_plain;h=2690233f317b87e7336b0404ae711837e726d5cf

Add a game phase to perform judging

This is after all answers are submitted, and before scores are computed.

The list of unique words are sent to each player so that they can
group them into sets of equivalent words.

The server isn't yet _doing_ anything with the word groups that are
submitted from judging, but that will be the next step.
