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
These variable names are confusing to read - they look somewhat like "version 10 rdinals" and "version 20 rdinals" - changing to "left" and "right" would avoid this.
