Subject: [PATCH] Remove popup for extension keyboard in landscape. bug:
 2519903

Also add a summary text in the input language list for languages with
a dictionary so that users don't feel cheated when they pick a language
that doesn't happen to have a dictionary. Remove greek as it isn't an
extension of the QWERTY keyboard.
