A lot of changes

- Fix the broken itemindex of ComboBox  in the Settings dialog
- Change from LCID to uint32_t
- Rewrite the headers of the lang related functions (can handle the whole LCID as input)
- Add dummy functions to unix.c
- Add proper combobox handling in win_settings.c
- Added a lot of debug calls temporarily
- Reactivate every disabled option related to language changes
- Move lang_id to 86box.h from win.h
- Implement on-fly resource switch as discussed with OBattler
- Reimplement everything language related in the initialization section of the program
- Implemented the ladder of three points
1, what is the --lang?
2, what are definied in the config? (to be implemented)
3, what is the system language
