Changes over 1.0:

User-side

Bumped project up to Godot 4.3
Completely reorganized UI, with more options
- Code previews added for the generated C++. These previews can be modified before being saved to disk, or even not saved to disk at all if you just need to generate, copy, and paste.
- Generating an output, saving that output to disk, and opening the folder of that output are now 3 separate buttons
- Settings button, settings window thereof coming Soon:tm:
Variable generation now supports initial values
Bugfix: Property binds now use proper Variant::Type enum entries
Boot screen is now light blue, cause I felt like it

Nearly complete codebase refactor, so that i's more uniformly organized for expansion of features in the future (eg. completing the full GDScript to C++ converter, adding a function binding generator, etc.)
Added intentional support for Godot 3. Not enabled yet due to a lack of a functional settings GUI
