Cherry-pick ff269c6d50 - Minor fixes to setup screen for 7"

(this conflicted and the automerger situation was a disaster, so I
  opted to skip immediately to help clear the backlog, now I'm
  cherry-picking manually)

 Using a TableLayout and large margins to shrink the input boxes causes
 weird artifacts when you type past the size of the input box. Fixing the
 padding is also not the right way, since stretching the input the whole
 screen length is ugly. Just use a width.
