Change melee weaponry rendering a bit

[Sunconure11]

Currently, some of the weapons are held rather awkwardly, and look weird as a result, regardless of texture size. Sabers are the main offenders, as are knives, and dirks. Smaller weapons such as knives and what not render rather largely when held. I created a minor pull request that might be worth toying around with, since it shows an example of what could be used to correct some of the rendering.
