Ships get a revamp!

Weapons are still, working, but basic! Scenery and ships are getting better each week tho!

Ships are now `bump mapped` with specular highlights too.

Added a model scale routine so I can (on the fly) scale any model up/down to fit my scene scale. Will prove handy for very large cruisers later on, as there coords can be limited to a max distance and I can just scale ship model down instead (giving the impression of distance!)
