* Fix Z value display
* Add HAS_PRINT_PROGRESS
* Alternative Info Screen option
* Add LCD_INFO_SCREEN_STYLE to example configs

* Allow override of soft SPI pins in `pins_*.h`
* Add default case to avoid compiler warning.
* Additional pin definitions for Archim 2.
* Einsy Retro has same timings as Einsy Rambo.

- Changed type of integer used for feedrate percentage from uint8_t to uint16_t.

- When LCD_SET_PROGRESS_MANUALLY was disabled and an SD print was not active (i.e. the printer was idle), progress_bar_percent would read uninitialized memory from stack and cause progress bar to jump wildly.
- Also updated conditions in `#ifdef` to match `ultralcd.cpp`

Some users may prefer to hide the position updates on the `LIGHTWEIGHT_UI` altogether. This leads to an even less cluttered display (it also saves on SPI traffic and one byte of RAM).

- Show units on lightweight status screen.
- Fixed progress bar so it works with M73

- This 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 makes it look less like a dash (idea stolen from cjsoong).

- This will slightly reduce the SPI requirements for
  updating the progress bar.

- Also deleted old implementation files which had been renamed.

- avr-gcc is more strict than the Arduino IDE, it seems.
