Improved translator for Biblatex and Biber

This translator is tailor made for working with Biblatex and Biber
I made the following tweaks:
- Set ExportNotes to 'false' (They can be very long, creating a lot of
trouble to Biber);
- Removed the comma separating each item (Biber saw it a as junk
character);
- Improved (or fixed) the regex to curly bracket protect the
capitalised words. This allows  correct rendering of capitalised word
when sentence case is required by the citation style.
