Changes to torch and delayer appearance (#669)

* plantlike, x-shaped torch
* removed separate LEDs for luacontroller since already contained in base mod it depends on
* changed delayer textures to be more consistent with other gates
* Reduced the amount of textures needed for pistons with texture modifiers. Will continue to work fine with all existing texturepacks. No change in graphics.
* use luacontroller_LED instead of microcontroller_LED to prevent breaking the digistuff mod which inherits it. I hope no mods inherit microcontroller LED.
