Send usb wakeup through ChibiOS

* New keyboard added

Zen is a split ortholinear currently in group buy.

* remove bad keymap

Keymap was throwing errors

* remove other bad keymap

I should have checked these before haha

* small fix to update folder name

* renamed temp

* renamed to zen

* update folder name

* Slim down matrix code

Suggested by drashna

* move KC_NO

* Update keymap

* change from rev2 to rev1

+Zen Keyboard
+====
+
+A split ergo keyboard with a few goals in mind:
+ - Be as thin as possible. Other split KBs (Let's Split, Nyquist, Iris) are 15.2mm thick. The Zen is only 8.0mm thick.
+ - Layout designed for gaming. 1.5u pinky keys, ortho alphas, and angled thumb keys. After trying Ortholiniear, Atreus62, and Ergodox, this is the best layout for gaming and typing.
+ - RGB backlighting. 16 WS2812b LEDs shine through the perimeter switches. The SK6812 variant are cheap and easy to solder.
+ - Price. Using Arduino Pro Micro, SK6812 LEDs, and PCB FR4 for the case, the cost of each half without switches or caps can be reduced to under $20 when purchased at volume.
+
+A build guide and more info for this keyboard can be found here: [Zen Build Guide](https://legonut.gitbooks.io/zen-keyboard/content/)
