New feature: advanced repair/dirt system

- items now have an internal repair value that can be lowered through damage taken. They can only be repaired up to that value by your mercs, onyl smiths can fully restore it to 100%
- guns get dirty over time, especially when shooting. Thsi can cause them to jam. Use cleaning kits (item #1576) to clean them by pressing 'Alt' + '.'
- more on this feature in http://www.bears-pit.com/board/ubbthreads.php/topics/308926/New_feature_advanced_repair_di.html#Post308926
- this requires GameDir revision 1496 or higher

WARING! THIS BREAKS SAVEGAME COMPATIBIITY!
