Make Menu Button less important

[SaurabhTotey]

The Menu Button has as much importance visually as the submit changes button. This shouldn't be the case because the submit changes button is a gameplay button and should be more important, whereas the menu button is more of a 'meta' button that brings up a menu that isn't pertinent to gameplay. I think this could be fixed by changing menu button from a text button to an image button using a pause icon.
