Updated the year of the copyright to 2014.
Added the option, removed_repeatable_field, to the repeatable field jQuery custom plugin, which allows to assign a function to removing field events.
- Added a jQuery plugin that increments/decrements a first occurring digit of a specified attribute value.
- Moved a part in a repeatable field script that was for the image field type into the own field type definition class.
- Fixed a bug in the repeatable field script for the image field type that removing fields did not update the preview and the button elements' ids.
Fixed a bug in the callback function of repeatable field events of the media field type that did not update the value of the id attribute when a remove button was pressed.
