- Changed IQ stanzas to pointer semantics
- Fixed commands from v 0.4.0 and tests
- Added primitive Result Sets support (XEP-0059)
- Tests for Result sets are not implemented yet. Result sets seem to be fairly unused across servers and is a little weird to test without a specific implementing XEP like XEP-0313; because the implementations are different across XEPs. Therefore, as 313 is coming, I'll update the tests for XEP-0059 with it.
