bundler_ext - renaming namespace
fixing test runs for jenkins and travis

When calling 'parllel:spec' with full options, one must specify the
number of cores to split the tests to. At first, I was manually giving
the number of CPUs, but then discovered I can pass '0' and parallel:spec
will auto-detect the maximum number of cores on a machine.
