This includes translations that were missing translations, with varying
extent between different languages, for the following things:
- "X mode is enabled" in-game warnings
- "Press {button} to freeze/unfreeze gameplay" for the level debugger
- Some credits strings for the post-2.4.0 extra Spanish options, the
PT_BR proofread, and Persian
- The recent gamepad menu changes (#1229)
Furthermore:
- "TAB" (used in the level debugger string) is now a separate string
instead of being hardcoded, because some languages needed it
translated
- Added missing arrows to Arabic/Persian font (needed for the gamepad
menu, and also a translator menu actually)
