While we wait on Lerdge X support to be merged into Marlin...how about getting the new TFT UI up and running?

I had to extract Lerdge's init sequence from the binary and do a few other things. Note, the UI is scaled for a smaller screen, a known problem we're going to fix, but here it is - touch and all.

I'm working with the dev who is doing the primary TFT support to make sure it'll run on the X (and K) out of the box. Next update will be when we have a proper sized UI to show off...
