- Some comments to refer to the XEPs added
- parseTimestamp method changed to use the XMLGregorianCalendar (refer to XEP-0082 and subsequently Date/DateTime definition of XML Schema Part 2, http://www.w3.org/TR/xmlschema-2/#date, http://www.w3.org/TR/xmlschema-2/#dateTime) a small test comparing the original implementation with the XMLGregorianCalendar implementation showed a significant performance improvement (about 0.1s on windows 7 64bit, AMD-A6 1.8GHz, 16GB RAM, Android Studio + Eclipse + Firefox running)
