Graham's Keymaps. (#2422)
* add my config * fix backlight, clean up that code * group background code, restore static var * qwerty is supposed to be in the middle * wrap layer change backlight in ifdef * backlight levels and some more 'emojis'. * Restructure to make it possible to press cmd ent on the right side of the board with one hand. * Expose the period through the number layer. Add Hyper keys to mouse layer * reduce mouse speed * add a : -P key * Thumbs up and down, remove some keys that are duplicated via function keys, clean up * fix build issues * add various emoji * duplicate default Meira keymaps * Miera updates * add documented but unmapped emoji * Sound for the Meira, was stumped by a file size! Thanks drashna! * add docs * docs * revert lib changes... * clean up * clean up * remove make file * Fixes missing key

+# Graham's Meira.
+
+Don't expect this to work for you unaltered! For the record, these are my notes, not a guide for you :-)
+
+## Known issues:
+Anything over 28k will begin to overwrite the boot loader, which is a pain!
+
+Be sure to check file size with:
+```
+avr-size meira_promicro_grahampheath.hex
+```
+
+## Sounds
+I've added a [8ohm 0.5W speaker](http://a.co/6MIKZSy), its a bit large, but it fits in approximately the same space as the ProMicro. I soldered directly to PC6 and GND.
+
+As the Meira code stood, adding sound increased the hex beyond what the boot loader could handle, so I had to dial way back on features that I wasnt using, like backlighting and RGB support. I also removed function keys, though I think you could restore some of these features, you certainly can't restore all of them and still fit with a boot loader.
+
+## Build
+
+Built for the ProMicro with:
+```
+make meira/promicro:grahampheath
+```
+
+Build and upload with, which is cool because it will sense your port.
+```
+make meira/promicro:grahampheath:avrdude
+```
+
+Program a hex directly with:
+```
+avrdude -p atmega32u4 -P /dev/tty.usbmodem14111 -c avr109 -v -e -D -U flash:w:meira_promicro_grahampheath.hex
+```
+
+If you use an AVRISP you will be program a hex without a boot loader:
+```
+avrdude -p atmega32u4 -P /dev/tty.usbmodem14111 -c avrisp -v -e -U flash:w:meira_promicro_grahampheath.hex
+```
+
+## Bricked
+Did you overwrite your boot loader?
+
+I did...
+
+I used an [Ardunio as an ISP](https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader), and was able to program various boot loaders. Ultimately it seemed like this was the right combo:
+
+[ProMicro pinout](https://cdn.sparkfun.com/assets/9/c/3/c/4/523a1765757b7f5c6e8b4567.png)
+
+[Wiring](https://forum.arduino.cc/index.php?PHPSESSID=467mm69btif69hdj5e3gil5465&action=dlattach;topic=363341.0;attach=145820): [via u/dmjlambert](https://forum.arduino.cc/index.php?topic=363341.0)
+
+ProMicro boot loader hex is called `Caterina-promicro16.hex` and is stored on [Sparkfun's GitHub](https://github.com/sparkfun/Arduino_Boards)
+
+```
+avrdude -c avrisp -p m32u4 -P /dev/tty.usbmodem14141 -v -e -U flash:w:Caterina-promicro16.hex -U efuse:w:0xcb:m -U hfuse:w:0xd8:m -U lfuse:w:0xff:m
