This commit addresses a range of changes, within scummvm subproject.
- Audio files, like mididrv, remove U32String based name and identifier, because ASCII only.
- mididrv.cpp had some wrong format for warning messages, fix those
- Message dialogs were modified to use default arguments more often, but reverting back to the orignal to minimize changes.
- SetTooltip has a fake constructor that takes in a string, and use it.
- U32Format had some break statements missing, add those.
- RemapWidget: Use fake constructor for setLabel and setTooltip, to make minimal changes
- SDL: setting text in clipboard no longer uses SDL_iconv_string
- TTS: Override base class "say" with strings, so tts->say can be used with normal strings too.
- About dialog: fix incorrect code for u32string variables
- Fix some extra brackets
- Some buttons were incorrectly removed from using translated labels, revert those
- Message Dialog: Pass default and alt buttons as const references
- Saveload Dialog: Use translations in missing places, use const-references. Also, use translations in a correct manner.
- Use const references for tooltip in GraphicsWidget, EditTextWidget, error.cpp
