Fixed some focus issues on Symbian.

There are really two bugs that are fixed in this commit:

- SetFocus() in Symbian does not automatically clear focus on the
  previously focused control, so we have to remember that control and
  clear it ourselves.
- Symbian assumes that it is always the control at the top of the
  control stack that should have focus, and if this isn't the case,
  focus may or may not work depending on whether Symbian has had a
  chance to reset the focus or not. Therefore, whenever we change
  focus on a control, we have to also readd that control to the top
  of the stack, to ensure that it stays focused.
