Backlight abstraction and other changes (#439)

* redoes matrix pins, abstracts backlight code for B5,6,7

* slimming down keyboard stuff, backlight breathing implemented

* don't call backlight init when no pin

* cleans up user/kb/quantum calls, keyboard files

* fix pvc atomic

* replaces CHANNEL with correct var in breathing

* removes .hexs, updates readmes, updates template

* cleans-up clueboards, readmes to lowercase

* updates readme

+TMK Keyboard Firmware Core Library
+==================================
+This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.
+
+Source code is available here: <https://github.com/tmk/tmk_keyboard/tree/core>
+
+
+Features
+--------
+These features can be used in your keyboard.
+
+* Multi-layer Keymap  - Multiple keyboard layouts with layer switching
+* Mouse key           - Mouse control with keyboard
+* System Control Key  - Power Down, Sleep, Wake Up and USB Remote Wake up
+* Media Control Key   - Volume Down/Up, Mute, Next/Prev track, Play, Stop and etc
+* USB NKRO            - 120 keys(+ 8 modifiers) simultaneously
+* PS/2 mouse support  - PS/2 mouse(TrackPoint) as composite device
+* Keyboard protocols  - PS/2, ADB, M0110, Sun and other old keyboard protocols
+* User Function       - Customizable function of key with writing code
+* Macro               - Very primitive at this time
+* Keyboard Tricks     - Oneshot modifier and modifier with tapping feature
+* Debug Console       - Messages for debug and interaction with firmware
+* Virtual DIP Switch  - Configurations stored EEPROM(Boot Magic)
+* Locking CapsLock    - Mechanical switch support for CapsLock

+
+Debugging
+--------
+Use PJRC's `hid_listen` to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
+
+You can use xprintf() to display debug info on `hid_listen`, see `common/xprintf.h`.
