❄ Introduce header and footer logic to search engine promos

❄ Introduce header and footer logic to search engine promos

* Add the ability to PromoDialog to be able to keep a header and footer fixed
  while the contents are scrollable.  Scrollable content is indicated by a never
  disappearing scrollbar indicator.

* Adds the ability to add a InfoBarControlLayout to the PromoDialogLayout.  This
  is used to standardize the buttons that are displayed across dialogs.

* Add the ability to add tags to the InfoBarControlLayout radio buttons.  These
  are needed because IDs aren't set for the radio buttons, and because it is
  safer to keep track of the search engine keywords with the RadioButtons that
  represent them.

Things to do:
- InfoBarControlLayout needs to move to the widget/ directory and be generalized
  so that they're not so infobar specific.

- Tests are in a separate CL.
