Custom Text View

[thecoolwinter]

Description

Replaces STTextView with a custom TextView implementation. Creates a new TextView and TextViewController classes that manage rendering text, handling text input, and keybinds. TextViewController replaces the STTextViewController class, connecting existing TextFormation classes, syntax highlighting, and other existing text view extensions.
