Support CORS/JSONP

I don't need this feature now but in order for the api to be used from browsers it must support either JSONP, CORS or both due to same origin policy (SOP) issues.

Create a shared persistency layer

Design a new structure in which ckanalyze-engine and ckanalyze-web share hibernate configuration

  • Migrate all hibernate configuration to the ckanalyze-jpa project.
  • Rename ckanalyze-jpa to ckanalyze-persistence

Livelock in ckanalyze-engine

Sometimes engine in multithreading branch goes in livelock.

Maybe CatSave object is the source of problems: it is shared, maybe should be synchronized
