Added getTranslatedLabel -- use this in UI rather than getSpanishLabel

Right now there is no difference between getSpanishLabel and
getTranslatedLabel, but it will make the program more extensible later
on.

I also added a Question class to help move code out of LocalTalk and
make it more readable. (haven't deleted the code yet so I don't break
anything, but you can call Question class methods instead of
LocalTalks)
