Revert "Experimental app list: Remove start page button."

This partially reverts commit 6af9260 (r293066).

(But we keep the ability to pass 0 to not have a button.)

oshima: Sorry about sending you this CL only to send you the revert. We decided
with the UI folks to remove this button and then today we decided to put it
back.
