**** NOTE ****
This code is very EXPERIMENTAL and UNSUPPORTED

See http://platformio.org/

Provide both long and short version strings

The long descriptor will still be available in M115

Centred the logo for 16x4 and 20 x4.
Moved version to the bottom line
Code shrink to 704 bytes.

Saves about 473 byte of progmem and 28 bytes of RAM.

Uses about 488 byte of progmem and 32 byte of RAM.
For that configurable.

- For some reason it’s easy to forget what BT stands for, but it
doesn’t need an abbreviation.

- The default serial baud rate of 115200
- The regular RigitBot bed size 254mm/248mm/254mm
- Single stock extruder
- Stock termistors for extruder and hotbed
- Stock Min X/Y/Z stops. Max stops not connected
- Stock 32 teth tooleys (stock axis steps)
- No auto bed leveling
- No screen

For consistency with other pins, allowing use of `PIN_EXISTS` macro.

- `SD_DETECT_PIN` replaces `SDCARDDETECT`
- `SD_DETECT_INVERTED` replaces `SDCARDDETECTINVERTED`
- Revise the description of `SD_DETECT_INVERTED`
- Add a note about the override of `SD_DETECT_INVERTED` in
`Conditionals.h`

- Rename the pin so it can be tested with `PIN_EXISTS`
- Fix some incorrect tests for `SDCARDDETECT`

For consistency with other pins, allowing use of `PIN_EXISTS` macro.

Apply `ENABLED` / `DISABLED` macros to files needing only a small
