Add bookmark app creation dialog.

This CL adds a dialog that is displayed when a user presses the "Create app
from this website" button in the wrench menu. The dialog allows the user to
customize the name of the bookmark app and set whether it opens as a tab or a
window. The dialog currently appears below the toolbar.

This CL also removes the old UI behavior of opening the app launcher or NTP
after creating the app because the dialog needs focus.
