Vita-saw Fix

The Vitasaw had ho sharp edges whatsoever making it look ugly.
And the fact that it had many completely useless polygons just added to it.

So i made a fix for this.
I removed 453 obsolete triangular polygons, and added sharp edges to where they should be.
Whilst i was at it, i also edited the UV mapping on the glass and liquid a bit, so you won't have ugly, visible lines on them.
