Added support for the following new options: dummy, fullscreenCrop, fullscreenTransition, imageTimeout, layerFollow, overlayBackground, responsive, touchTransition, trueFullscreen, wait.

Added a short documentation hint about automatic type conversion of boolean values to the README.txt and below custom option fields.

node_reference support: Use all image/media fields of referenced fields if nothing else is configured.

This replaces a long overdue workaround which loaded the images for a node_reference gallery directly from the database instead of using the Field API.
It's now possible to select multiple image/media fields to show when formatting a node_reference field.
At the same time we got rid of the 'galleria_' prefix for the field formatter settings which requires an update.php run to adopt the old settings.

Issue #1290076 by Antiblank: Fixed endless loop when searching for themes when the library folder can not be opened.
Also added a hint message to the 'Advanced settings' page when the library folder does not exist.

Also: restructured it for better readability and fixed some minor errors.

"In general, this property should only be used by large multi-module packages, or by modules meant to extend these packages, such as Fields, Views, Commerce, Organic Groups, and the like. All other modules should leave this blank."

This fixes an error with JS compression where the theme isn't loaded automatically just by embedding the theme file.

Fixes warnings reported by the Coder module.

Galleria can now display fields of type 'media'.

* Reordered some functions for better readability.
* Removed CVS $Id$ tags.
* Removed whitespace on line-endings.
* Added newline at end of file.
* Fixed some comments.

Renamed "zoomed" -> "normal" and "preview" -> "thumbnail" image styles to be consistent with Galleria internals.
Also: optimized translatability of the "Original image" text used when no image style is set.
