Color UI, Classic UI and MKS UI

Classic UI	Color UI	MKS UI

Main props for Classic UI is better multi-language support ( as example cyrillic fonts does not works for Color UI yet ), all control goes through bottom buttons. Graphical classic UI comes from character LCD based displays thats why it looks like it looks. Less useful but consume less space. Color UI is new generation of Marlin UI and it was introduced in 2019 and it really pretty looking and easy controllable UI.
