Add support for the KC60 v2.0 2015-09-12 (#360)

* Don't save the ctags file in the repo.

* Initial support for the KC60 board. Only 5x5 working so far.

* Rename because this isn't the same KC60 as others.

* Add in some generic layout.
Pins seem to be in the right order except the 6th column spews
gibberish.

* Don't need this for now.

* Move this to some other folder.

* Trying again to start over.

* Don't need to start over because I figured out why the 'broken' stuff wasn't working.

* Attempt to enable backlighting. It's on on pin B7 like other boards.

* Fix last port changes and fix LED control in keymap.

* Trying some other LED code.

* Bootloader needs to be bigger. Disabling backlight for now.

* Simplify LED code while I try to figure it out.

* Turn back on backlighting.

* Backlighting works now. Just need to get levels or breathing working.

* Trying to allow for turning off the LEDs before I get to brightness levels.

* The missing link: need to run the init_ports function for LEDs to work properly.

* Removing breathing stuff since it bricks the board.

* Clean up default layer.

* Cleanup keymap, KC60 doesn't support a 5th right bottom-row button.

+kc60 keyboard firmware
+======================
+
+## Quantum MK Firmware
+
+For the full Quantum feature list, see [the parent README.md](/README.md).
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboard/kc60 folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file. 
+
+Depending on which keymap you would like to use, you will have to compile slightly differently.
+
+### Default
+To build with the default keymap, simply run `make`.
+
+### Other Keymaps
+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `<name>.c` in the keymaps folder, and see keymap document (you can find in top README.md) and existent keymap files.
+
+To build the firmware binary hex file with a keymap just do `make` with `KEYMAP` option like:
+```
+$ make KEYMAP=[default|jack|<name>]
+```
+Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
