 - Add request timeout argument

+===
+- Fix Python 3 bytes/str incompatibility: use response.text instead of response.content so simplejson (required dependency) receives a str
+- Fix receive_verify_post to use the dict returned by get_body() directly instead of calling json.loads on it again
+- Fix get_signature_string returning bytes instead of str; encoding moved to get_signature_hash where hashlib requires it
+- Sync version string across __init__.py, sailthru_http.py User-Agent, and setup.py
