HttpPoster fix and Blackberry port initiation

Fixed issue with the HttpPoster which wasnt working at all initially.

STARTED THE BLACKBERRY PORT.
logging is working perfect as well as the caching. Still experiencing some issues with the networking (returning InterruptedIOException).
The BB port depends on the JME RMS caching method for now as a temporary resort (in a way less flexible compared to the Blackberry's persistence storage). The native persistence would be incorporated once the networking is fixed.
JME's logging approach is the preferred logging option (as stated clearly in the BB SDK docs), so it remains unchanged.
