Add option to only track time when there are significant changes

[frcroth]

Set the new application.conf option webKnossos.timeTrackingOnlyWithSignificantChanges to false to disable time tracking for changes where only camera movements happened.

Note that the timeTrackingPause is still active, so if there are “significant changes” within that duration again, the timespans will be extended.

Steps to test:

• Set option to true, no time tracking for moving cam and saving
• Set option to false, time tracking for moving cam and saving

Issues:

• fixes Improve measurement of spent time for tasks/annotations #7543

• Updated changelog

Looking good! I don’t think we need to group the config keys just yet. Please see my comment about simplifying the boolean expression

Nice!

I wrote a follow-up issue for proofreading annotations, since they don’t get “automatically” time-tracked anymore if this new config option is true. #7637
