and added autoplay_slideshow.

Previously titles have been shown although ``show_title`` has been set to
``False`` in ``prettyphoto_properties``.

- Finish update to 3.1.2 by updating css and images and adding the new `pp_default`
theme (which is the new default btw ;-)

------------------

- Upgraded to prettyPhoto 3.1.2 and implemented two new properties:
deeplinking , social_tools
[petschki]

------------------

- Upgraded to prettyPhoto 3.0.3 .
This fixes thumbnails in overlay_gallery partly because the regular expression
now looks for a (jpg|jpeg|png|gif) within the whole url. if your originaly
linked images are completely without this, they still wont show up.

- fixed overlay_gallery property defaults to "False"

------------------

- Upgraded to prettyPhoto library including it's css and image sprite to 3.0.1
to fix issues with jQuery 1.4.4 (see http://bit.ly/hxYUrt) which is shipped
with latest Plone 4 by default. This fixes 2.

- Added 'overlay_gallery' and 'slideshow' as additional configuration options
but disabled by default cause of a bug in jquery.prettyPhoto.js which avoids
displaying thumbnails not ending on (jpg|jpeg|png|gif).
