Tweak Text Editor to fit better with the rest of Blender 2.8:
- Move sidebar to the right
- Add proper context menu
- Move view toggles to the View menu
- Change the indentation option to be an enum between spaces and tabs
- Several layout tweaks
Patch by @tintwotin / Peter Fog with additional tweaks by me.
