Cockpit Specular Map Test

We decided, that while the fighters are too small to need a specular map, the cockpits would look a lot better with them.  One of the earlier versions of the Eterium 3.0 engine supported specular maps, but that had been removed as we abandoned support.  I have added back specular support for cockpits.  While it works, there is still some tweaking required.  Here is a screenshot with the new specular map on the Talwar cockpit.
