Cranium's Preonic layout

This layout is based on the Preonic default with some changes I find interesting to share.

• As a Colemak user, Capslock was rebound to Backspace.
• Escape was moved to the top-right of the keyboard
• Enter was moved to the bottom-right of the keyboard. It's now easy to hit and can even be activated with the palm.
• An F12 was put next to the left CTRL => it's the shortcut I use to toggle the Guake terminal.
• I don't really use the key below my Escape (top-right, 2nd row), so I'll consider any ideas for the moment.

Lower

• Perhaps one of the most interesting change: the arrow keys were moved to the right-hand home row, activated with the Raise layer. It means I can use the arrow keys without moving my hand from the home row, by activating the Raise layer with my thumb. It took a while to adapt but it was totally worth it. To note, I also put Home/End on the same layer but one row below, with I also find really useful.

• The "arrow" keys act as Vol+/Vol-/Previous/Next on the Adjust layer (which is quite a natural mapping for these media keys).
