Pronto integration

Integration of pronto required to add few new gems and to update some of the gems. The old method which provided the linter launching was reworked to launch pronto which provide the linter launching. The output of pronto is the result of all linters. The pronto result is transformed into a structure which match the original one. This integration required to change few tests and add new ones.
