Remove button uppercasing

[kazlauskis]

Automatic uppercasing of words breaks Greek words that have accents.

On the buttons with the Greek text where you have capital letters you have also accents. Please delete all the accents as in Greek the capital letters do not take any accents (unless the accent is on the first letter of the word).
