AdjudicationFrameworkRefactoring (#176)

This test rewrites the AdjudcationFramework such that:

MinimalAdjudicationFramework contains code that should be within any adjudicationFramework(removing/replacing arbitrators via fork)
Then there are Adjudicationframeworks that pull and push(pulling ones are the ones where users can make a question against, while pushing ones are price feeds.)
These frameworks allow for a more customised Adjudcationframework building via inheritance.

If you have better names for the adjuciationFramework blocks, I am all ears. Your previous AdjudicationFramework was deleted, but AdjudicationFrameworkForRequestsWithChallengeMangement contains the same code.
