new method [I]?MetaModelFilterSetting[s]?::getReferencedAttributes() which is needed for #131.
Needs to be implemented in the child classes yet.
Darn, should save in IDE before comitting. This adds the missing brackets. ;)
First version of the "Clear all filter" element.
Update for "hide clear filter" option.
First shot of swapping the stdClass attribute based render settings with a real class.
This enables feature #132.
Merge branch 'rendersetting_attribute' of github.com:MetaModels/core into rendersetting_attribute
