Rhbz1124630 - remove RESTEasy dependency from client

by switching to jersey as JAX-RS implementation, in fedora we could save users 200MB download.

Depend on zanata/zanata-parent#36

Not really depend on this but it's nice to have (especially in preparation for Fedora packaging) zanata/zanata-api#22
the console class(in fact an interface with a mock version in testing) has encapsulated colour output and syntax etc. Using System.out won't give those. You are right with the safety side. But that method is just a shortcut to do printf plus newline. I can make the method not to do % interpolation when there is no extra arguments (behave like a println) or do you think it's worth adding extra methods(println, print plus all other message type decorator which is quite a lot)?
