Revert commits I73d4fb85,Ie1458920 from CAF merge

Revert commit 96360fc85 "Launcher: change the stype for UX launcher" to restore the
Search Bar. This will be added as an option to the Launcher menu in the future.

Revert commit 738ab7d74 "Launcher: Set Apps name in main menu list marquee" because
apps with names that are just long enough to reach the fade-out point look like the
last letter is missing a part.
