Update ZRTP4J library that supports SHA384, modify algorithm selection scheme to better

conform to proposals in ZRTP draft, add class and functions to support ZRTP configuration
(GUI will follow some time later).
This version was tested with Phil's new (not yet released) Zfone3, is also compliant to
existing Zfone.
Update lightweight crypto library, it contains SHA384 now.
Some smaller updates in ZrtpTransfomEngine to match changes in ZRTP4J.
