* jf sync mode master could return idle when stopped and so not all modules return the same value and must check for 'stopped or idle', Also must throw if any of the module gives an error
* added contains_only to sls::Result (#827)
* added variadic template for checking if a result contains only specified values
* fix for gcc4.8
* renamed to Result::contains_only
* updated condition in Detector.cpp
* stop on only the positions
