Made script to control editor camera with keyboard

I made this script to make it easier to move the camera in the editor through use of the keyboard. Thought some of you might want it also. If you have an object selected, the camera will align to it, if you have multiple objects selected, the camera will align to a median point of all selected objects and if you have nothing selected, the camera will align to a point just in front of it.

Must be placed in a folder called "Editor" anywhere inside your assets folder.

The controls are Alt+1/2/3/4/5. 5 toggles orthographic.

This is actually pretty useful. I spent a while simplifying the code (and testing it and fixing it and simplifying more), and I rather like how it came out. I believe it does essentially the same thing, but puts them as shortcuts you can bind under Scene View, rather than menu items.

(I guess I changed the order and default keys too, I didn't like isometric so close to orthographic, I hit it by accident.)
