Corrected wrong behavior on Safari when text input field value is the default value, it was unselected on mouseup event following click event; removed non functional code to select field on shift click because focus event is always triggered before click event and does not give access to mouse button state (another difficulty is that selection is remembered on each input field which would make shift click selection sticky).
Rewritten index for better integration with AXEL web site.
Merge branch 'master' into gh-pages
