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
Instead of "push" I think it would be better to use "upload" in all these strings. I think it would also be better to explicitly say "source files" and "translation files" in these strings.
