Correct typo in priority label
Merge branch 'dev'
Update to SilverStripe 3.1

Now all the static properties are private: modify accordingly.
Update templates to silverstrap-dev
Support sortable and zoomable features

Updated the module to be able to sort the images with drag&drop: now
there is an hard dependency on sortablefile [1] and a soft dependency on
colorbox [2].

Rewrote and improved the overall design.

Merge branch 'master' of entidi.com:silverstripe-gallery into dev
Remove double GalleryImage
Use fotorama instead of ad-gallery

Ad-gallery seems to be no more maintained. I badly needed touch support
and fotorama provides all what I needed (apart colorbox support).

I quickly tried many galleries and fotorama is my choice. The following
list contains some of the viable alternatives:

- [bxSlider](https://github.com/stevenwanderski/bxslider-4)
- [GalleryView](http://www.spaceforaname.com/galleryview/)
- [Jssor slider](http://www.jssor.com/)
- [JCarousel](http://sorgalla.com/jcarousel/)
Improve template modularity

Now ContentGallery.ss does not depend on silverstrap anymore.
doc: update to lastest changes

Actually the fork diverged too much from the original project to be
considered derived work, so clarifying it in the README.
composer: update
Add references to README

Included links to freshly opened issue tracker and added more info to
the README. Put references on official repositories.
Include COPYING license
Add support for Colorbox

Allow to zoom the images with a click if Colorbox is present.
Use better markup for gallery containing

The resulting gallery was too close to the following text and was
exceeding in width the container width. Enclose the gallery inside
<div class="lead col-md-12"> to solves these issues.
