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

-## Plugin installation
-
-There is a bunch of plugins shipped with Shaarli, where there is nothing to do to install them.
-
-If you want to install a third party plugin:
-
-  * Download it.
-  * Put it in the `plugins` directory in Shaarli's installation folder.
-  * Make sure you put it correctly:
-
-```
-| index.php
-| plugins/
-|---| custom_plugin/
-|   |---| custom_plugin.php
-|   |---| ...
-
-```
-
-  * Make sure your webserver can read and write the files in your plugin folder.
-
-## Plugin configuration
-
-In Shaarli's administration page (`Tools` link), go to `Plugin administration`.
-
-Here you can enable and disable all plugins available, and configure them.

-
-## Plugin order
-
-In the plugin administration page, you can move enabled plugins to the top or bottom of the list. The first plugins in the list will be processed first.
-
-This is important in case plugins are depending on each other. Read plugins README details for more information.
-
-**Use case**: The (non existent) plugin `shaares_footer` adds a footer to every shaare in Markdown syntax. It needs to be processed *before* (higher in the list) the Markdown plugin. Otherwise its syntax won't be translated in HTML.
-
-## File mode
-
-Enabled plugin are stored in your `config.php` parameters file, under the `array`:
-
-```php
-$GLOBALS['config'['ENABLED_PLUGINS']]('ENABLED_PLUGINS'].html)
-```
-
-You can edit them manually here.
-Example:
-
-```php
-$GLOBALS['config'['ENABLED_PLUGINS'] = array(]('ENABLED_PLUGINS']-=-array(.html)
-    'qrcode', 
-    'archiveorg',
-    'wallabag',
-    'markdown',
-);
-```
-
