Updated signup view

I added a signup view with a scroll view so you can edit all the text
fields with out the keyboard covering it up. i also added a file that
allows you to change the system font, right now its set to the default
you are welcome to change it to see what looks best, but you will
probably have to change the label sizes for some of the fonts (ex
Copperplate). i have added notes so if you have any questions about
anything let me know.
