Generate HTML documentation using MkDocs (WIP)

MkDocs is a static site generator geared towards building project documentation.
Documentation source files are written in Markdown, and configured with a single YAML file.

 * http://www.mkdocs.org/
 * http://www.mkdocs.org/user-guide/configuration/

Ref. #312

* remove pandoc-generated HTML documentation
* move markdown doc to doc/md/,
* mkdocs.yml:
  * generate HTML doc in doc/html
  * add pages TOC/ordering
  * use index.md as index page
* Makefile: remove execute permissions from generated files
* Makefile: rewrite htmlpages GFM to markdown conversion using sed:
   awk expression aslo matched '][' which causes invalid output on complex links with images or code blocks
* Add mkdocs.yml to .gitattributes, exclude this file from release archives
* Makefile: rename: htmldoc -> doc_html target
* run make doc: pull latest markdown documentation from wiki
* run make htmlpages: update html documentation

+## Foreword
+
+There are two ways of customizing how Shaarli looks:
+
+1. by using a custom CSS to override Shaarli's CSS
+2. by using a full theme that provides its own RainTPL templates, CSS and Javascript resources
+
+## Custom CSS
+
+Shaarli's appearance can be modified by adding CSS rules to:
+- Shaarli < `v0.9.0`: `inc/user.css`
+- Shaarli >= `v0.9.0`: `data/user.css`
+
+This file allows overriding rules defined in the template CSS files (only add changed rules), or define a whole new theme.
+
+**Note**: Do not edit `tpl/default/css/shaarli.css`! Your changes would be overridden when updating Shaarli.
+
+See also [[Download CSS styles from an OPML list]]
+
+## Themes
+
+_WARNING - This feature is currently being worked on and will be improved in the next releases. Experimental._
+
+Installation:
+- find a theme you'd like to install
+- copy or clone the theme folder under `tpl/<a_sweet_theme>`
+- enable the theme:
+    - Shaarli < `v0.9.0`: edit `data/config.json.php` and set the value of `raintpl_tpl` to the new theme name:
+      `"raintpl_tpl": "tpl\/my-template\/"`
+    - Shaarli >= `v0.9.0`: select the theme through the _Tools_ page

+## Example installation: AlbinoMouse theme
+
+With the following configuration:
+- Apache 2 / PHP 5.6
+- user sites are enabled, e.g. `/home/user/public_html/somedir` is served as `http://localhost/~user/somedir`
+- `http` is the name of the Apache user
+
+```bash
+$ cd ~/public_html
+
+# clone repositories
+$ git clone https://github.com/shaarli/Shaarli.git shaarli
+$ pushd shaarli/tpl
+$ git clone https://github.com/alexisju/albinomouse-template.git
+$ popd
+
+# set access rights for Apache
+$ chgrp -R http shaarli
+$ chmod g+rwx shaarli shaarli/cache shaarli/data shaarli/pagecache shaarli/tmp
+```
+
+Get config written:
+- go to the freshly installed site
+- fill the install form
+- log in to Shaarli
+
+Edit Shaarli's [[configuration|Shaarli configuration]]:
+```bash
+# the file should be owned by Apache, thus not writeable => sudo
+$ sudo sed -i s=tpl=tpl/albinomouse-template=g shaarli/data/config.php
+```
