* K8200: new folder in example_configurations for Vellemann K8200 (3Drag
clone - should work with 3Drag too, please report)
* K8200/language.h: updated machine name and URL for K8200
* K8200/Configuration.h/Configuration_adv.h: updated manually with
parameters
form genuine Vellemann Firmware "firmware_k8200_marlinv2" based on the
recent development branch
* K8200/files by Vellemann: added folder with original files from
Vellemann homepage, since there is no GitHub fork you could link to by
them
I tested the changes on my K8200 with 20x4-LCD and Arduino 1.0.5 for
Windows - everything works well
