Tracking id for users

[snoyface]

Users should have some way to distinguish which dot is thiers. We can accomplish this by having "you are number 5 (or whoever number) On the client interface and displaying "5" above thier dot on the wall.

We should assign colors. For now let's have them static. A stretch goal could be to allow users to pick their color (either on the client or on screen... on client probably preferred, I have a color picker I wrote for Tree of Life we can use).

It may be difficult for people to discern ~60 different color variations. In order to keep it to a maximum spread, we'll need to allocate colors in a manner similar to hard drive file allocation tables, avoiding fragmentation and gaps. So if users take up colors 1-50, and then 48 of those disconnect so only colors 1 and 50 are used, the next person would need to reuse one of the colors that became available again rather than going to color 51.

See also #6. If we're already drawing a constant marker for each player that shows even if they aren't currently painting, we might be able to use that as a way for them to keep track of their "brush".
