Gemfile update

Updated Gemfile.lock dependencies to more recent
Updated zeus and added zeus config files
Locked down Rspec to <3.0, because of too many deprecations
Updated jasmine config files
about Gemfile: 
zeus is already in the Gemfile, some people are using it.  The upgrade does not touch are code, but fixes issues with zeus.
rspec -  upgrade does not break our tests, but already gives deprecations, which is good, because we can start fixing them and prepare for ver 3.0 gradually.  I do not see why really should keep the current version.
