RAFAEL_SOL_MAKER's RGSS2 TO RGSS3 FIXES v0.2

#===============================================================================
#        RAFAEL_SOL_MAKER's RGSS2 TO RGSS3 FIXES(Work-in-Progress) v0.2
#_______________________________________________________________________________
#   Description  | Some fixes if you plan to put your Ace game to run on RGSS3.
#                | It was proven it's not hard at all, and there are some
#                | advantages, like a faster and better Ruby, improved Audio
#                | classes, creation of bitmaps with more than 2048x2048 pixels,
#                | using a exclusive (and coding flexible) layer to autoshadows,
#                | and some other cool features.
#________________|______________________________________________________________
#     Usage      | Plug it above any custom scripts, below default engine ones.
#________________|______________________________________________________________
# Specifications | Difficulty to Use:
#                |  * (almost none at all)
#                | Scripting Difficulty:
#                |  * * ½ (I particularly don't recommend to edit it)
#                | Compatibility:
#                |  ??? (it's already made to create compatibility!)
#                | New Methods:
#                |  - Tilemap.passages
#                | Overwritten Methods:
#                |  - (none)
#                | Aliased Methods:
#                |  - Game_Map.setup
#                |  - Window_Base.initialize
#                |  - Spriteset_Map.create_tilemap
#________________|______________________________________________________________
#  Known Issues  | This is a W.I.P. version, so, it's expected to be incomplete.
#                | Probably with more tests some problems and bugs can appear...
