Factored the generation of JSON serialization from beeing part of the mirror... 

Factored the generation of JSON serialization from beeing part of the mirror objects into a seperate class. The purpose of this is to make it easier to change the serialization to contain object identification and references.

Added a test case for the script mirror and modified a number of the other mirror tests.
