GroupRelationType relationship permissions have been renamed

The entity between a group and entity will henceforth be referred to as a relationship. The rules of said relationship (old GroupContent) are now the relation (old GroupContentEnabler). So the methods and permission names change accordingly in Group 2.0.0.

Before:

• Permission to update the relationship itself: update my_plugin content
• Permission to update the grouped entity: update my_plugin entity

After:

• Permission to update the relationship itself (changed): update my_plugin relationship
• Permission to update the grouped entity: update my_plugin entity

This applies to all permissions of the sort. Please check both your code and config files (especially GroupRole and View entities) for old permissions.
