Changes:
- Added: Undo/Redo. WARNING: Does not include Texture painting.
- Improved: Sped up loading of Venue by dynamic loading of Icons done when required rather than when validating XPacks.
- Improved: Reduce unnecessary recalculation of unaffected tracks after a terrain height change.
- Improved: Moving cursor focus from control to control was triggering unnecessary calculations when values were not altered.
- Improved: Fastkeys added for Open/Save/Undo/Redo.
- Fix: Deleting the track on which Start Positions were attached caused error.
- Fix: Deleting User-created Material (that was previously used in the Venue), then reloading Venue (without having Saved) would cause error. Materials are now saved only when the Venue is saved.
- Fix: On a new Venue, S/Objects couldn't be added until the terrain had been altered.
- Fix: Set rFactor Vertex color.
- Fix: String Object align-to-track function wasn't using "cut" version of terrain/track.
- Fix: Object – Manually setting position didn’t keep height above ground.
- Fix: Removing all the Materials from the Track Surface resulted in a crash.
