Moved core ui to its own folder.
Worked on theming (proper light and dark theme)
Began to work on the scroll box widget and input box constructions
I added back a script for flattening the codebase: gen_flattened_codebase.ps1
I now generate the layout the compiler wants, eventually I'll just have a custom policy so that the compiler can accept the non-idiomatic layout
See scripts/build.ps1 & gen_staged_compiler_codebase.ps1 for how this is handled.
