Aesthetic changes.

Made the 'readme' box(stage) more symetrical and appealing. Also made it so the user can't edit the outputted text. The scroll bar now defaults to the top of the readMe
and not the bottom as well.

Made the 'change user' stage text, input field and button alignment better. Also the stage now closes when you press OK.

Made the 'connect' stage text, input field and button alignment better. Also the stage now closes when you press OK.

Made the 'update' stage text align and appear better.
