Big merge from doug (#139)

* binary store count

Fix issue in binary store object count

* update V10aa/other for testing

* update V10aa/other for testing

* reenable buffer dumping

* update V to 10ac for testing

* Additional diagnostics

Additional output of CPU usage for each module when stopping

* V 2.02.10ad for testing

Fixed issue of finding correct raw data block

* Tidying

Lots of GUI improvement and code tidying. Functionality to export
gzipped documents to reduce traffic.

* V 2.02.10ba for user testing

* Tidy up click selector

Improve layout and tips on dialog and improve logic for manual and
automatic event types.

* Menu tide up

* Update nilus maven for PAMGuard

* Fix reprocess choices

Make sure the choice to continue anyway is always present.

* Improve start of binary file timing

Code to better get binary files to start right on the hour when processing files offline rather than half a sec or so later.

* Fix early data discard

Fix issue in clip generator: when running very fast offline raw data being discarded before clips are generated. Changed threading model slightly and increased data keep time by 2x the thread jitter to try to avoid this.

* Update pom to JSerialCom 2.11.0

* V2.02.11e fix file start skip

Skipping start of files was causing click detector to not find clicks. Changed code so first seconds are still sent, but with data set to 0, rather than not sending data since that was causing sample counts in different bits of PAMGuard to get out of synch.
