AppController: Fix height of search mode header.
AppController: Fix height of search mode header.

The search header is bigger than the default header, but the outer
.header div wasn't expanding, only the inner content. Then the
scrollable portion overlapped the bottom edge of the header. The height
of the .header in searchMode is now 56px instead of 48px.
