RTPS: Added new locator kinds and upgraded to latest set of ids

Browse Source 
The standard says that UDPv6 is the index 2. However, the dissector
contained the old implementation of RTI DDS (which had SHMEM = 2
and UDPv6 = 5). I have updated the dissector to be compliant with
the standard and indirectly be compliant with the new version of
RTI DDS which now implements the standard in this aspect.
