Enable Drop Caps for Firefox HTML compatibility mode

Drop Caps tab was disabled in paragraph options when Firefox was
selected in HTML compatibility options and Writer was in HTML
editor mode. There is no need to do that. Firefox and all modern
browsers will display drop caps correctly if they are exported
from LibreOffice.
