Title: Polymer switchover

This CL fixes the default UI to be Polymer. It also hides the "Switch UI" context menu item by default.

The default UI can still be temporarily enforced locally by modifying the value of DEFAULT_UI_ in background.js.

Also, the "Switch UI" context menu item can be temporarily brought back by modifying the value of CAN_SWITCH_UIS_ in background.js.
