Fix 32 bit / 64 bit multiplayer interop problem

Browse Source 
- Fix gids to be calculated the same on 32 bit and 64 bit platforms.
  Previously they were byte offsets into a pointer array, which meant
  multiple of 4 on 32 bit platforms, and multiple of 8 on 64 bit platforms.
  Now they are indexes.
