dengitor-v0.4.4

This is the first release 🥳

The editor is very basic (and buggy!) with just a handful of features:

1. Changing transform component and camera component
2. Changing the current entity
3. Changing theme (Breeze Dark, Breeze Light and System default) and font (might be blurry on Win32) from Edit->Preferences
4. Switching between scene and game view
5. Change scene view options like FOV and scene grid
6. About page in Help->About

NOTE: Don't close any window with 'x' on Windows. This will destroy the window which is currently buggy
