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
I think it will be unclear to translators that `%s` will show the version number here. We could add a comment that translators can see, but it might be better to just improve the grammar:

`Version %s of the client is now available. You should update your client.`
