Allow macros in entity statements.
As yet macros were only allowed in the `rules` statement. This limited their usefulness rather strongly. By allowing macros in `entity` statements many of the limitations are removed. It is currently not possible to also allow calls to macros in other collector statements, because the may only contain literal rules and no entities. However, as a macro can contain either a literal rules or entities they cannot be allowed in collectors. This would either require a check if the content of the macro is allowed at the current position or two types of macros have to be introduced one for entity rules and one for literal rules. In order to prevent the inadvertent introduction of inconsistencies by later changes of the schema, the `entity-rule` group was removed and replaced by direct references to the `entity` element.
