rhbz1110627 zanata init

https://bugzilla.redhat.com/show_bug.cgi?id=1110627
and https://bugzilla.redhat.com/show_bug.cgi?id=1038852

Depends on https://github.com/zanata/zanata-api/pull/15 and https://github.com/zanata/zanata-server/pull/520
We could also add a message after this to tell the user the workaround since they can't use zanata init right now (they might not have time to wait for server upgrade). Maybe links to help pages like:

 - Project Creation: http://zanata.org/help/projects/create-project
 - Version Creation: http://zanata.org/help/projects/create-version
 - Configuring the Client: http://zanata.org/help/cli/cli-configuration
