Support Croatian keyboard

Basically Croatian keyboard is QWERTZ layout with extra letters such
as č, ć, đ, ž and š.  This change just introduces Croatian keyboard
subtype and QWERTZ layout which has the extra letters as popup mini
keyboard of base letter.

It might be great if we could have dedidated table layout.
