v1.0 - Public release

This does a number of things over the original extension by pr6i6e6st:

• Fixed the distance-remaining calculation bug reported by Zygmunt Molotch
• Added alternate database storage nodes that provide greater accuracy for FG Classic to allow my Disease Tracker Extension to function correctly in FG Classic.
• Changed behavior of double-clicking "Add" so that months and years in this row will now work.
• Assigned default values to every variable I could find to avoid nil errors.
• Fixed some weird way of writing the data path that might only have worked in Classic or something like this. Zygmunt Molotch had issues in Unity.
• Added a chat message if the program can't get the current date. The message suggests that calendar might not be configured.
• Some travel fields had "delaykeyupdate" which means that typing in a number of hours traveled and then clicking the travel button didn't use the entered number unless you clicked out of that field first. I left this on Traveled and Distance because otherwise you get 'incremental changes' to the Remaining number, but removed it from speed and number of hours.
• Decrement effect durations when advancing time via the Time Manager panel.
• Increase minutes when advancing rounds in combat (1/every 10 rounds).
