Changes

• Fairly significant overhaul of the processes used to persist data to disk. This should translate to a significant reduction in the possibility of data corruption to sequences and profiles (and other things too).

Fixes

• Fixed a visual issue where moving an event would leave it progress text behind.
• Fixed an issue where altitude locked start and end times may choose the wrong time when multiple valid times are available.
• Fixed an issue where an auto focus override filter could appear to be set to a filter, but is actually set to nothing.
