Device settings: add Croatian lang to keypad settings

Based on map where SYM is ALT and OK is CTRL.
Adds Croatian diacritic letters: C/c, S/s, Z/z with acute and caron (Čč, Ćć, Šš, Žž) and D/d - crossed D (Đđ)
All letters are accesible by pressing ALT except letter "Ć" which is accessed with CTRL.

CTRL key is not processed consistently in some apps or parts of them - sometimes it types letter 'Ć', sometimes it copies text, on other occasions it does nothing. Typing in browser or chrome beavior differs in address bar and input fields inside web pages (e.g. google/yahoo searh input field). I'm not sure why this is happening but such behavior is not limited to this change.
