Change "Bill to" into "Quote to" in quote templates

Hi

i was little confused and found that there are two terms that don’t go together on the same document…

On Quote you have Bill to… We need to add one more string in language files so we can translate it accordingly…

It shoud be in english Quote for not Bill to (its ok on actual invoice) in localisation is a no go…

So please add in next version for Quotes separate string so we have string quote_for and bill_to for translation
