Kokua:Release Notes/Kokua Release RLV/5.1.3.43064

This version is aligned with LL viewer 5.1.2 and RLV 2.9.23.

This release continues the refactoring work from the previous release with a number of internal fixes where we either made a mistake in refactoring or decided after seeing the result that we preferred Kokua's previous way of doing something.

There is one fix of note which is the main reason for this release - Area Search was broken in the previous version.
