[WIP] UI rewrite, code cleanup

[BocuD]

I'm currently working on slowly refactoring and cleaning up the UI code, currently focussing on the configuration menus. I'm opening the PR to open discussion about the topic, as this is not ready to be merged yet (though it should be identical functionality wise to the current release)
The goal is to later on be able to add and change various features building on top of new / improved UI code, but i want to limit this PR to cleaning up and improving code, without making any feature changes for now.
I realize that getting this merged at some point is a tough ask, but i am still making the PR as I want to put in some time and work on this codebase, and i feel like doing so is a better approach than "another fork".

What has been done so far:

• Refactored a lot of code in CActConfigList to remove the large tPressEnter method body, which was entirely comprised of if/else statements based on the currently selected button. This functionality is now achieved using an Action instead.
• Fixed an issue causing DTXCreator to not compile depending on compiler settings (removed half width katakana delegate names)
• Add a few missing translations so all non localized versions of methods can be removed fully
• Cleaned up unused and legacy constructors in CItemBase and inherited classes
• Switch log output to Unicode
• Use system language instead of system locale to determine display language
• Add methods for BindConfig() to CItemBase, which can be used to map methods to save and load data
• Removed a lot of the code from tRecordToConfigIni and tUpdateDisplayValuesFromConfigIni by moving the implementation to each element (using BindConfig())
• Change version display and
• Split up CActConfigList into a partial class
• Remove unused Option stage
• Create a new UI system based on a hierarchical system:
  • UI elements are drawn as part of groups
  • Groups can contain more elements
  • Elements can be toggled
  • Elements are drawn relative to their parent
  • Elements are transformed, rotated and scaled using matrices (also relative to parent)
• Documentation in various places; adding english documentation
• Renaming a lot of japanese variable names to be more concise and in english
• Rework quick config and sort menu to use new UI system
• Remove some smaller unused older classes such as CDTXVersion and Folder
• Remove plugin system (as far as i am aware this is not actually used anywhere by anything or anyone, if this isn't the case reverting this commit should be easy)
