Merge branch 'Lua-video-lib-expansion' into 'next'

Browse source 
Lua video lib expansion

New video/drawer library functions for hud.add to use:

v.width() and v.height() return the screen width and height respectively (in other words you get the screen resolution), while v.renderer() returns the string for the renderer used ("software", "opengl", or "none").

Possibly add more stuff later, but for now these things at the least can be merged in next
