AnHardt d0e24e0876 Adaptive screen updates for all kinds of displays 
The target here is to update the screens of graphical and char base
displays as fast as possible, without draining the planner buffer too much.

For that measure the time it takes to draw and transfer one
(partial) screen to the display. Build a max. value from that.
Because ther can be large differences, depending on how much the display
updates are interrupted, the max value is decreased by one ms/s. This way
it can shrink again.
On the other side we keep track on how much time it takes to empty the
planner buffer.
Now we draw the next (partial) display update only then, when we do not
drain the planner buffer to much. We draw only when the time in the
buffer is two times larger than a update takes, or the buffer is empty anyway.

When we have begun to draw a screen we do not wait until the next 100ms
time slot comes. We draw the next partial screen as fast as possible, but
give the system a chance to refill the buffers a bit.

When we see, during drawing a screen, the screen contend has changed,
we stop the current draw and begin to draw the new content from the top.

Example Configuration for Vellemann K8200

  • Configuration files for Vellemann K8200 (with VM8201 - LCD Option for K8200)

  • K8200 is a 3Drag clone - configuration should work with 3Drag http://reprap.org/wiki/3drag, too. Please report.

  • updated manually with parameters from genuine Vellemann Firmware "firmware_k8200_marlinv2" based on the recent development branch

  • VM8201 uses "DISPLAY_CHARSET_HD44870_JAPAN" and "ULTIMAKERCONTROLLER"

  • german (de) translation with umlaut is supported now - thanks to @AnHardt for the great hardware based umlaut support

I @CONSULitAS tested the changes on my K8200 with 20x4-LCD and Arduino 1.6.12 for Mac (SD library added to IDE manually), 2016-11-18 - everything works well.
