Add placeholder heat gradient texture.
Integrate loading and using the heat gradient texture with the MultiMaterial.
Flip the UV coords in the shader
Set heat gradient amount and normal from Ship.
Do some monkeying around to move the quality enumeration into Material.h so that we don't need to include gl2 headers.
Also clean the model materials of their heat gradient specialParameter0 settings.
Decided that these are safer being a class static member.

Remove the heat gradient from the loader and move it to the ship where I'm already doing material setup!
Add an else case for objects using the heat gradient stuff but where it's not being setup.
Modified the heat gradient texture so the hull goes white long before it explodes.
Transform the direction of the heating by the normal matrix... the result is incorrect but at least it's not view dependent!
Added matrix uploading to the Uniform class.
Added a heatingMatrix member to transform the heatingNormal by the inverse of the ships viewTransform.
Thus getting it into the models local space (I think that's right!).

Single commit back-port of Salwans 3D Cockpit feature from Paragon.
Set the Wave to use the "cockpit" model - which I'm adding as a mod currently.
Have it try to set the cockpit when a ship is initialised rather than on construction so that it works when the ship is changed by buying/selling or through scripts.
Fix a bunch of line endings.
Commented on the distinction between rendering everything before and after a certain point.
Should probably rewrite some of this and have distinct phases in the rendering like a proper game would!
Remove the offset as I no longer need it.
Merged across Salwans latest updates, adds  lag to the movement of the cockpit when maneuvering or accelerating.
