Text handler overhaul (ASCII/UTF-8, Multilang, Fonts)

[AloXado320]

Courtesy of HackerSM64, this massively changes text and dialog handling, replacing the old vanilla method.

Changes mentioned

• Changes the vanilla text systems to support ASCII and UTF-8 encoded text.
• Textconv and the charmaps have been completely removed.
• Adds in proper multi-language support for all four languages, easily toggleable with config files.
• Adds new characters required for all languages to work, as well as some extra characters.
• Adds a full diacritic system allowing all accented characters to be used easily.
• Every character can be used in every language, even Japanese characters if the define is enabled.
• Text printing functions have been optimized and given new features such as alignment, escape characters, %s in dialogs.
• Vanilla menus have been reworked in order to utilise sprintf and text alignment better.

Additional changes to be added for this repo:

• Font textures organized in their own folder in segment2.
• Compatibility with vanilla text and "special" dialog strings.
• Proper Japanese and Chinese support.
• Language font override, as a separate struct.
• A small font extractor for all versions of the game, with fixed positions.
• Each version defined should set it's own language only unless multi-language it's defined.
• Color control command text as a separate define.
• EU texture rectangle dialog rendering as a define.
• Typewritter effect as a define.
• Better menu scrolling options as a define, without relying on options menu.
