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.

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

+### Main features
+Shaarli is intended:
+ * to share, comment and save interesting links and news
+ * to bookmark useful/frequent personal links (as private links) and share them between computers
+ * as a minimal blog/microblog/writing platform (no character limit)
+ * as a read-it-later list (for example items tagged `readlater`)
+ * to draft and save articles/ideas
+ * to keep code snippets
+ * to keep notes and documentation
+ * as a shared clipboard between machines
+ * as a todo list
+ * to store playlists (e.g. with the `music` or `video` tags)
+ * to keep extracts/comments from webpages that may disappear
+ * to keep track of ongoing discussions (for example items tagged `discussion`)
+ * [to feed RSS aggregators](http://shaarli.chassegnouf.net/?9Efeiw) (planets) with specific tags
+ * to feed other social networks, blogs... using RSS feeds and external services (dlvr.it, ifttt.com ...)
+
+### Using Shaarli as a blog, notepad, pastebin...
+
+ * Go to your Shaarli setup and log in
+ * Click the `Add Link` button
+ * To share text only, do not enter any URL in the corresponding input field and click `Add Link`
+ * Pick a title and enter your article, or note, in the description field; add a few tags; optionally check `Private` then click `Save`
+ * Voilà!  Your article is now published (privately if you selected that option) and accessible using its permalink.
