general optimization's with 0.1.1

factor the factory game has updated to version 0.1.1 So lets discuss the changes.

Removed bug where some menus stay on screen after closing them.

This bug happens when you open a menu twice however when closing it will only close one instance of the menu. 

How did solved this? Insted of directly removing widget from screen we get all widgets of a class and run a for each loop on that and remove them all 

Made sure the light on generator menu showed up under the right circumstances.

Changed the vertical order

Removed a bug where when you were not looking at anything and had a miner in world it world open miner widget

If you were looking at nothing and pressed e it would open the miner menu. The reason this happend is because when you press E it does checks to see what you are looking at and at the bottom of the checks is the miner. If you look at the miner and press E it opens miner however if you look at nothing and press E because of shit code it still opens. I fixed the shit code
