Change background runtime without rebuild

1. Please define CTRL_TOGGLE_BACKGROUND or "Toggle background" in MENU_CUSTOM. You can toggle among "Image", "Transparent", "No background", and "Opacity".

2. Change your background image. For example, "ln -sf $HOME/.config/evilvte/bg2.jpg $HOME/.config/evilvte/background.png"

3. Toggle background to "Image", then you have the new background.

Notice: Un*x does not care what the filename is. You can rename or link a .jpg file to .png to fit your build-time BACKGROUND_IMAGE setting.

Just wanna see my defined background without ctrl . at beginning.

So I switch the order.. 

It's better have an option to select user defined background or desktop background or nothing at beginning.

thanks!
