FIx INI parser usage in multiple .cpp compilation units linked together.
If A.cpp and B.cpp both include "INI.h" they each export the same functions causing one definition rule violation during linking stage.
To avoid this problem, templated methods implementation has to be declared 'inline' and other supporting functions 'static'.
Because class static member
INI::PARSE_FLAGSis not constant, it should be initialized only once. Currently each .cpp that includes the header is doing the initialization and generates undefined initialiation order error. Those variables need to be static per compilation unit.API change:
class static members
INI::PARSE_FLAGSINI::SAVE_FLAGSmoved out of class and renamed/made into static global variables, that can be initialized to unique values in each compilation unit.
