Some minor changes to the layout to save space and remove dangerous functions

This is only a proposal, and I hope that it is acceptable. I commented on every change, so that you know why I messed with things. (most changes are more important on low-res devices or in landscape view)

Is there a way to reduce the spacing between the menu icons? I could not find anything, but those 4 icons take up so much space that I can only read the first letter of XPrivacy next to the app's icon on the left.
