Less skidding, more FPS (hopefully) and some flowers

What's new:

• Increased quadcopter acceleration and deceleration, so it starts moving quicker and "skids less".
• If you press the beam button while the blueprint menu is open but you are not over a work area, the blueprint menu will close. This allows cancelling blueprint selection.
• Grass tiles randomly have flower decorations spawned on top of them.
• Performance improvements (fewer draw calls via selective effects).
