Make keyboard hints a better visible

Patch Set 1: User were complaining about not seeing the hints
             at bad light conditions. Change color of the hints to
             'holo_blue_light'

Bring back productivity for QWERTZ keyboards

Patch set - 1
http://review.cyanogenmod.com/#/c/24532/1
changed the productivity for QWERTZ keyboards in a bad way
because rowkeys_qwerty2.xml was also used as 2nd QWERTZ row.

For de_DE 'ä' and 'ß' are far more usual then '@' and '#'
Also exchange '$' with '€'

I hope this doesn't break other locales using QWERTZ

Patch set -2
Also use 'rowkeys_qwertz2.xml' for the 600dp and 768dp layouts
and enable AdditionalMoreKeys for row 1 on QWERTZ keyboards
