Big refactor. CrowdTask is now JobConfiguration. CSV and Template are saved separately in Session. Combined MechanicalTurkService and CFService into Job. Included htmlsimpledom via composer.json.
Added validation rules (errors are shown in submit tab)
Added toHTML() to JobConfiguration.
Prepared job retrieval: added command:retrievejobs for using commandline, made changes to mturk to retrieve full objects and to crowdflower to fix judgment glitch. Unit_id is now in relation_direction/relation_direction_multiple template to propagate ID's.
Sort function working with simple ascending/descending
custom php and results view added
