Implement VCanvas and Update TextElem

- Text now requires a font and is able to take an individual scale
- Container requires &ref for Elements to make sure they always exist
- SetViewport now sets the canvas as well
- SetBaseViewport Sets the Virtual Canvas Size
- Layout Now requires a Drawlist reference in Render function
- main.cpp: updated the template
