make gl.Texture safer in LuaIntro
remove Spring.UpdateInfoTexture
modularize InfoTexture handling (move away from BaseGroundDrawer)
this also adds new lua gl.Texture("$info:height") etc.
add new shader->LoadFromLua("file.lua")
it loads a vertex & fragment shader from a single lua file with equal syntax as gl.CreateShader takes
+ it adds a new `textures` subtables
new shader based InfoTexture (faster, shinier & modular)
massive speedup in CGameHelper::TestBuildSquare() for a much faster F2 view
