Updating doco on static resource serving
Fix latex document generation.

 * don't try copying files from not-existent _static/ directory
 * comment-out latex_logo definition and remove references
   to `.static/logo_hi.gif` both from latex_logo and html_logo
 * work-around a buglet in sphinx.writers.latex.LaTeXTranslator
   whose visit_reference method doesn't recognize `irc://...`
   as a URL reference.
Insert options needed to enable epub generation.

the only mandatory option is epub_exclude_files, since
epub generator cannot cope with javascript files.
Use a explicit :exclude-members: option

and enable the :members: option on .. autoclass:: SelectWidget too.

Add support for html5 native time-related widgets

  * for the DateInputWidget, the .datepicker interfered with
    the native widget shown on field enter

  * the DateTimeInputWidget's template defined the input field
    as being of type "text" instead of "datetime"; therefore,
    the native datitime widget was never shown

To enable the correct behaviour, the jqueryui datepicker will be
activated only after detecting the native support for the respective
input type is missing via a custom generated modernizr.js.

The installed version of modernizr.js was generated enabling only detection
of input types and attributes; this way, the filesize is just 2394 bytes,
instead of 15483 of the full minified distribution.
Let the user set rendering preferences

for both DateInputWidget and DateTimeInputWidget:

 * default rendering as html5 input with jquery fall-back
 * if prefer_jquery is set, render as jquery-enhanced text input
Define a "prefer_html5" attribute for all widgets

and use that preference to enable native rendering of date and datetime
