Remove Empty On-Click Methods

[MattMoradi]

There are a ton of empty button click methods with names like button_click that contain no code. These are generated when simply double clicking a component in the visual form editor and were probably clicked by accident.

Although Ctrl+Z would normally fix this problem, they are a bit more difficult to remove after compiling and might need to be removed manually. This is not a high priority but would make a good code cleanup.
