DoubleX RMVXA Variable Pointers

#    Lets users set some variables to point to some other variables            |

#  * Variable manipulations                                                    |
#    1. $game_variables.var_pointers[var_id] = [pointer_val, chain_flag]       |
#       - Sets the variable with id var_id to point to the variable with id    |
#         pointer_val if pointer_val is an integer greater than 0              |
#       - Sets the variable with id var_id to stop pointing to any variable if |
#         pointer_val isn't an integer or is less than or equal to 0           |
#       - When a variable isn't pointing to any variable and the former's      |
#         being read/written, only it'll be actually read/written              |
#       - When variable A points to variable B with A's chain_flag as false or |
#         B not pointing to any variable, and A's being read/written, only B   |
#         will actually be read/written instead                                |
#       - When variable A points to variable B with A's chain_flag as true and |
#         B pointing to variable C with B's chain flag as false or C not       |
#         pointing to any variable, and A's being read/written, only C will    |
#         actually be read/written instead                                     |
#       - When variable A points to variable B with A's chain_flag as true and |
#         B pointing to variable A with B's chain flag as true, both A and B   |
#         effectively points to their respective selfs instead                 |
#       - When a variable points to itself, it effectively doesn't point to any|
#         variable                                                             |
#    2. $game_variables.var_pointers[var_id][0] =                              |
#       $game_variables.var_pointers[var_id][0].to_s                           |
#       - Deactivates the pointer behavior for variable with id var_id while   |
#         still keeping its pointer record with its chain flag                 |
#    3. $game_variables.var_pointers[var_id][0] =                              |
#       $game_variables.var_pointers[var_id][0].to_i                           |
#       - Activates the pointer behavior for variable with id var_id using its |
#         pointer record with its chain flag                                   |
