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
Why does this do two things? I am not sure of the value of this over separate `setAllProjects(...)` and `setFilteredProjects(...)` methods - this way makes the name confusing.
