- Entity templates are now per-player, along with an unowned "unmodified" version of each template that should be used to find the original values of the stats. This can be accessed in the scripts as <template>.unmodified. - Fixed a pathfinder crash when the last path from the engine had 0 elements (just ignoring this for now). - Units should no longer become purple when they upgrade in rank. Refs #3. This was SVN commit r3863.
