Track pending moves in GSP

[domob1812]

With the new PendingMoveProcessor from libxayagame, we should implement custom logic to track pending moves in the Taurion GSP. The information we need (for now) is waypoints of characters that are being moved, as well as new characters being created.

The format of the pending data could be like this:

{
 "characters":
   [
     {"id": 123, "waypoints": [...]},
     {"id": 456, "waypoints": [...]}
   ],
 "newcharacters":
   {
     "name": [{"faction": "red"}, {"faction": "blue"}],
     "other": [{"faction": "green"}, {"faction": "green"}]
   }
}
