Don't initialize Figures time before FixOldFileVersions, also don't allow LogAction to reset Figures.time.

Fixes to initialization order to allow FixOldFileVersions to run (and save) before figure windows are initialized.

Some fixes from mitosis branch: Don't run ChangeTrackID if current and desired track are the same and avoid (startHash <= 0), also fix in ProcessNewborns to reflect GetHullID returning 0 if no hull is found.
