Dave Jones 7ba06c9e0d Dave's custom keymap
This moves the keys closer to a traditional layout with some redundancy
around the middle to compensate for fast non-traditional typists like
myself who tend to wander from the home row a fair bit. Navigation keys
are provided in layer 2 (accessed by left thumb button), programming
symbols and classic numeric keypad in layer 1 (accessed by right thumb
button). Permanent layer switching is provided with a smaller thumb
button. Ctrl provided in place of caps lock (because no-one needs
caps/num lock), space, backspace, enter, shift all in traditional
positions with layer 1 providing things like equals, tilde and
apostrophe (an attempt to re-use existing muscle memory).

LEDs are pimped to the point of being silly (fading in/out on layer
switch, rolling on reboot ... because I can). Power and reset keys
provided on left thumb pad in layer 2.

No meh or hyper as I haven't found a burning need for them yet.
