ergodox_ez: Update my keymap to v1.3

This updates my ErgoDox EZ layout to v1.3, which has the following
noteworthy changes:

* Added support for logging keys, by pressing `LEAD d`. Also included is
  a tool to generate a **heatmap** out of the logs.
* The arrow and navigation keys were rearranged again, and now require
  an additional key being held to activate. See the **base layer** for
  an image that shows where arrows are.
* The **experimental** layer has been redone, and is now
  called **ADORE**, and as such, can be enabled by `LEAD a` now.
* Switching between Dvorak and ADORE is now persisted into EEPROM, and
  survives a reboot.

+## Heatmap
+
+When the keypress logging functionality is enabled (by `LEAD d`), the keyboard will output a line every time a key is pressed, containing the position of the key in the matrix. This allows one to collect this information, and build analytics over it, such as a heat map, including dead keys too.
+
+Included with the firmware is a small tool that can parse these logs, and create a heatmap that one can import into [KLE][kle]. To use it, simply point `tools/log-to-heatmap.py` to a base layout file (one is included in the `tools/` directory), and the key position log. The latter one can create by running `hid-listen`, and redirecting its output to a file.
+
+ [kle]: http://www.keyboard-layout-editor.com/
+
+The generated heatmap looks somewhat like this:

 # Changelog
 
+## v1.3 - 2016-07-06
+
+* Added support for logging keys, by pressing `LEAD d`. Also included is a tool to generate a [heatmap](#heatmap) out of the logs.
+* The arrow and navigation keys were rearranged again, and now require an additional key being held to activate. See the [base layer](#base-layer) for an image that shows where arrows are.
+* The **experimental** layer has been redone, and is now called [ADORE](#adore-layer), and as such, can be enabled by `LEAD a` now.
+* Switching between Dvorak and ADORE is now persisted into EEPROM, and survives a reboot.
