cer 7.x-3.0-alpha6

Major changes have occurred in this version of CER.

REMEMBER: In order to register new classes with the autoloader, please clear your caches and tip your waiters before running update.php.

• CER presets are now exportable, fieldable entities, and their configuration options are fields. All your existing presets will be converted by this update. The point of converting presets to entities is to streamline CER's code base, ease the port to Drupal 8, and leverage other modules' support for entities (i.e., Views, Rules, and other modules built on top of Entity API). This also makes presets compatible with PHP 5.2 (#2273251: Cannot save preset in php 5.2). You will need to re-export any CER presets you have exported in code using previous versions of CER!
• Parts of CER's core code have been moved into a new bundled module called Field Object, which is automatically enabled by the update. This module provides a field type that can reference a field instance, and is used by presets to store the left and right fields.
• Support for Hierarchical Select, as well as the dependency on it, has been completely dropped in favor of simple select lists. It may return at some point in the future, but for now it's very awkward to get it to work with Field Object. #2251117: Remove Hierarchical Select dependency or provide fallback to simple nested select
• The CER Entity Settings add-on module has been completely rewritten in order to address various problems and the lack of forward compatibility. It now uses fields and has a hard dependency on Entity Reference. There is no upgrade path from the previous version, so you will lose all your saved entity settings. Unfortunately, an upgrade path will not be possible, due to the reformulation of presets as entities. This change should address #2281285: CER entity settings not preserved when working with Commerce products.
• Online documentation is now included via the Advanced Help module.
• #2244561: CerFieldHandler::log() throws EntityMetadataWrapperException if there's no "url" property
