Add a line to the compass heading dive menu that shows the currently set heading to enable the diver to confirm it / add it to notes. Also add a log entry every time a new compass heading is set or the heading is cleared. And add a way to add compass headings to the log without changing the currently set heading - this was added after discussion with cave divers who are interested in recording headings when mapping out caves.

The builds are for testing purposes only. Be careful, they might not work and are definitely not recommended for real dives.
