This sort of pImpl inheritance code code was weird, I got rid of it
and added a new pointer in the TileSet class instead.

Lua only supports the "double" type for now, so storing a 64-bit integer
would lose information unless it's encapsulated in a more complex type.
I prefer to disable these accessors for now.
