Add an Ergodox Colemak Mod-DH keymap for french layouts

[Colemak Mod-DH](https://colemakmods.github.io/mod-dh/) layout for
users keeping an `azerty` layout configuration on their OS.

The symbols layers was done after analysing various programming
languages sources codes and should be close to optimal for typing
confort.

+# French hacker layout
+
+## Introduction
+
+[Colemak Mod-DH](https://colemakmods.github.io/mod-dh/) layout for
+users keeping an `azerty` layout configuration on their OS.
+
+This keymap is for users keeping their operating systems configured with
+`azerty` - for typing passwords or in their native languages - but who
+wants a Colemak Mod-DH layout on their mechanical.
+
+The symbols layers was done after analysing various programming
+languages sources codes and should be close to optimal for typing
+confort.
+
+Special macros for [Qubes OS](https://www.qubes-os.org/) are included.
+
+There is an accented characters layer for infrequent typing of french
+accents.
+
+Special macros for [Qubes OS](https://www.qubes-os.org/) are included.
+
+## Build
+
+    cd keyboards/ergodox
+    make french_hacker
+
+## Design explanations
+
+See my [blog post](http://dialectical-computing.de/blog/blog/2017/01/29/a-better-coder-layout-for-the-ergodox-ez-keyboard/).
