The JDB Util dependency has been upgraded to 3.4 from 2.0. This includes
backwords-incompatible changes in the LightOptionParser class used by this
project. I need to re-write that code to use the newer version of
LightOptionParser.
* Added a UUID field to TimelineMarker.
* Updated StreamBasedTimelineSource to read and write UUIDs. The current format
is compatible with the 1.x format, but support for the 1.x format is planned
to be deprecated for 3.x.
The UUID is added on the same line as the timestamp, with a `,` separating
the timestamp and the UUID value.
* Updated JDBLabsWebTimelineSource to use UUIDs to reconcile the different
timestamp entries (more reliable that using the timestamp value).
