Update some untranslated and mistranslated messages and text from VBA GX.
Match Wii Controls was mistranslated as "Wiimote con Nunchuk", but since this readme https://github.com/dborth/vbagx#readme shows about many ways for match Wii controls with Wii remote only and not just Nunchuk, i've replaced it with "Coincidir controles Wii".
* Updated spanish language translation
The text is organized in alphabetical order.
The texts for the interface are the first and the texts for Snes9x GX were moved at the end to have a better order and facilitate translation into other languages.
* Updated spanish language translation
Translations have been added for the text "Chinese (Simplified)" and "Chinese (Traditional)".
