Add new SubStyles and their available keyword lists to specific languages:
- Enable 8 Scintilla's SubStyles (each), which allow for new keyword lists and styles for the languages with SubStyles available: ActionScript, ASP, Bash, C, C++, C#, GDScript, Go, HTML, Java, JavaScript (standalone and embedded), JSP, Lua, PHP, Python, Resource (RC), Swift, TypeScript, and XML.
- The new SubStyles have been added to `langs.model.xml`, `stylers.model.xml`, and the themes, which means users can just use the StyleConfigurator for the SubStyles, just like they do for the original Styles.
