Description

Currently there in project two kinds of localization files: STR (where all messages of all languages assembled into one file; used in core engine) and MSG (where messages split by language). This PR overhauls localization both frameworks.

Both frameworks now exports their functions to DLL API, so CHECKSUM is changed. OSIRIS scripts has huge internal changes, which may make them incompatible with legacy editor script generator.

Additional Comments

There some additional changes to OSIRIS checksum generation. I'm still planning to rewrite save/load functions with platform independent serialization, but some features of these are required right now.

Added serial_version field to tOSIRISModuleInit to solve problem when CHECKSUM is different on various platforms and environments due variadic size of structs.
