Added support for map/layer mask
A custom "Mask" property on a layer or a "foregroundXmask" property on a map can now be used in combination with the SMSG_MAP_MASK to dynamically disable certain map layers from the server. Feature previously seen on ManaPlus and implemented for Mana client for compatibility. Also added a ResourceRef class for automating the Resource reference counting. Closes #44
