The ability to decode DIS PDUs with Wireshark is great!

Unfortunately, it takes a calculator to decode the timestamps.  But no more! 
Timestamps using the attached patch (based on SVN trunk version 26034) are
displayed as follows:
   Timestamp = MM:SS mmm absolute (UTM)
or
   Timestamp = MM:SS mmm relative
where M is minutes, S is seconds, and m is milliseconds.

This is in accord with 'IEEE Std 1278.1-1995' section 5.2.31.

Files changed:
 * epan/dissectors/packet-dis-pdus.c
 * epan/dissectors/packet-dis-fields.c
 * epan/dissectors/packet-dis-fields.h

Description of change:
The DIS timestamp was treated--essentially--as a generic unsigned int of static
size (4).  This change adds and calls a timestamp specific decode function:
parseField_Timestamp().
