New features

This release adds support for PHP 7, fixing a fatal error happening on that PHP version. Besides a few small bug fixes, there is also a new feature: a plugin called "Encoding/decoding" has been added with which you can encode or decode PHP serialize, JSON and Base64.

This version of Entity Queue helps the UX of managing queues, as well as trying to clarify the configuration of queues. It also adds basic validation to prevent queues from overwriting changes if the same queue is modified by multiple users.

**Changes since 7.x-1.2**

Primary Improvment

Nothing much here. Some cleanup, some test fixing. Commited: Issue #2922465 by wizonesolutions: Make backend plugins reusable

This will get used in conjunction with some upcoming work, but for now it's just sitting there with tests.
