Added a light-weight status screen for the ST7920

Browse Source 
- The status screen uses the ST7920 character generator to greatly
  reduce SPI traffic and MCU load when updating the status screen.

- Has been tested with the RepRapDiscount Full Graphics Smart Controller
  but should work with any LCD that uses an ST7920 or fully compatible
  controller.

/* This is an implementation of a status screen for the RepRapDiscount
* Full Graphics Smart Controller using native ST7920 commands rather
* than using U8Glib.
*
* This alternative status screen makes use of the built-in character
* generation capabilities of the ST7920 to update the status screen
* with less SPI traffic and CPU use. In particular:
*
* - The fan and bed animations are handled using custom characters
* that are stored in CGRAM. This allows for the animation to be
* updated by writing a single character to the text-buffer (DDRAM).
*
* - All the information in the status screen is text that is written
* to DDRAM, so the work of generating the bitmaps is offloaded to
* the ST7920 rather than being render by U8Glib on the MCU.
*
* - The graphics buffer (GDRAM) is only used for static graphics
* elements (nozzle and feedrate bitmaps) and for the progress
* bar, so updates are sporadic.
