Redone save system to use chunk system that was originally going to be implemented in a0.0.0_2.0, but with some code commented-out since the loading system is still the same, except for the fact the appropriate chunk file is loaded instead. As a result, the world size has decreased to 256x256 until a0.0.0_2.0 to prevent having to redo the loading system entirely as the loading system worked perfectly before this version.
The map is now saved and loaded from luafiles/client/Empiralist/Map_data/EMPM1/MapChunk_1_1.dat.
Fixed an issue where only the main home menu name would be used for all menus, instead of the menu name corresponding to the current menu that is open.
Note: This should be the last update before the switch from 2.5D to 3D, so it will be a good while before the next update if another emergency update does not have to be made.
