Subject: [PATCH 03/16] Add one-hand support.

This adds an action, `ACTION_SWAP_HANDS`, that swaps the the keys on the keyboard across a keymap-defined hemisphere in order to support one-hand typing without requiring a separate one-handed layer. See updated `doc/keymap.md` for more information.

+### 2.6 Swap-Hands Action
+The swap-hands action allows support for one-handed keyboards without requiring a separate layer. Set `ONEHAND_ENABLE` in the Makefile and define a `hand_swap_config` entry in your keymap. Now whenever the `ACTION_SWAP_HANDS` command is executed the keyboard is mirrored. For instance, to type "Hello, World" on QWERTY you would type `^Ge^s^s^w^c W^wr^sd`
+
+The configuration table is a simple 2-dimensional array to map from column/row to new column/row. Example `hand_swap_config` for Planck:
+
+```
+const keypos_t hand_swap_config[MATRIX_ROWS][MATRIX_COLS] = {
+  {{11, 0}, {10, 0}, {9, 0}, {8, 0}, {7, 0}, {6, 0}, {5, 0}, {4, 0}, {3, 0}, {2, 0}, {1, 0}, {0, 0}},
+  {{11, 1}, {10, 1}, {9, 1}, {8, 1}, {7, 1}, {6, 1}, {5, 1}, {4, 1}, {3, 1}, {2, 1}, {1, 1}, {0, 1}},
+  {{11, 2}, {10, 2}, {9, 2}, {8, 2}, {7, 2}, {6, 2}, {5, 2}, {4, 2}, {3, 2}, {2, 2}, {1, 2}, {0, 2}},
+  {{11, 3}, {10, 3}, {9, 3}, {8, 3}, {7, 3}, {6, 3}, {5, 3}, {4, 3}, {3, 3}, {2, 3}, {1, 3}, {0, 3}},
+};
+```
+
+Note that the array indices are reversed same as the matrix and the values are of type `keypos_t` which is `{col, row}` and all values are zero-based. In the example above, `hand_swap_config[2][4]` (third row, fifth column) would return {7, 2} (third row, eighth column).
+
+
+
 ## 3. Layer switching Example
 There are some ways to switch layer with 'Layer' actions.

+kitten_paw keyboard firmware
+======================
+This is the firmware for the 2016 revision of the Kitten Paw controller by Bathroom Epiphanies.
+Most of the boilerplate code is the work of [BathroomEpiphanies](https://github.com/BathroomEpiphanies).
+
+NKRO doesn't work at the moment, I don't know if I will take the time to find out how to fix this, so far 6KRO is enough for me.
+
+## Quantum MK Firmware
+
+For the full Quantum feature list, see [the parent readme.md](/doc/readme.md).
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboards/kitten_paw 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 a folder with the name of your keymap in the keymaps folder, and see keymap documentation (you can find in top readme.md) and existant 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 **__keymap.c__** and are stored in folders in the `keymaps` folder, eg `keymaps/my_keymap/`

+# ErgoDox EZ Steno Configuration
+
+This layout has a layer that uses the TxBolt Stenograph protocol over a Virtual Serial port. It requires something like Plover in order to function.
+
+In Plover, you can select TX Bolt as the Stenotype Machine, and find the COM port that was assigned. In this way, your regular keyboard will still function normally, and you can switch back and forth between the Steno and Keyboard layers.

Subject: [PATCH 16/16] quantum: Move qk_ucis_state to process_unicode.c

In order to not declare the same variable in multiple objects (which
happens when building UCIS-enabled keymap for both the ErgoDox EZ and
the ErgoDox Infinity), move the declaration to the .c file, and keep
only an extern reference in the header.

Many thanks to @fredizzimo for spotting the error in Travis, and
suggesting the fix.
