Better implementation of automatic range generation.
Makes sense to run updateRange on any select element regardless of scope, providing is has the range attribute.
Allow generated ranges to go both ways rather than just ascending.
Added wildcard option for the current year.
Added range generation for named months.
Cleaner use of jQuery to create option elements and append them to the selector.
Implemented automatic updating of 'day' selectors.
Fix: Correctly parse the monthIndex to an integer to prevent string appending.
