v1.0.0-dev/server): Added "update" reasons

These "update" reasons will call .Next() and perform updates on screen.

Common "update" values:
- "move player" (Call .Next() and redraw each time the player moves)
- "time <duration>" (Call .Next() and redraw if needed, given the duration)
- "ping" (Call .Next() and redraw each time a ping packet is received)
