gdp: It's about time we bump the version number.

Browse source 
Original commit message from CVS:
* libs/gst/dataprotocol/dataprotocol.c:
(gst_dp_header_from_buffer), (gst_dp_packet_from_caps),
(gst_dp_packet_from_event):
* libs/gst/dataprotocol/dataprotocol.h:
* libs/gst/dataprotocol/dp-private.h:
It's about time we bump the version number.
Since event types don't fit in the guint8 anymore describing
the payload type, make payload type 16 bits wide.
