Title: .is_date_format? slightly improved (rspec included)

changes:

* removed method `.is_date_format?` from Cell (it wasn't used, and a duplicate of the similarly named method on Workbook
* changed num_fmt to downcase before any other processing (some files use uppercase formatting for dates)

(rspec included, total +3 (still the same 42 failing))
