Paste should result in a clean Markdown code

* jquery.htmlClean.min.js: * in order to paste from any(?) document

* rangy-selectionsaverestore.js: required by hallo html cleanup

* App.master: * A link to awesome fonts
* a hint, to engage to invoice :-)

* rangy-core.js: using the bower installed one

* to-markdown.js: using the new code, came from the `npm start`
  process

* Edit.aspx: fixes copy/paste from LibreOffice writter colored text.

* Web.csproj: using new javascript references to:
rangy-core, rangy-selectionsaverestore jquery.htmlClean

* mdd_help.htm:
* mdd_styles.css:
* rangyinputs-jquery-1.1.2.js: obsolete
