Now it is possible to
1) Define metadata classes that describe arbitrary metadata.
Meta-classes has all the capabilities of regular classes and
in addition has 3 new attributes: Cardinality, Applies and Inherited
2) It is possible to attach meta-class instances to packages,
classes (including other meta-classes), properties, methods and
method arguments. Each of them got new "Meta" key containing
list (or single scalar) of meta-class instances
Implements: blueprint metadata-in-muranopl
