User:Trappist the monk/CS1 maint: Date and year

This is an AWB settings file and custom module that editors may use to assist in clearing. CAVEAT: This code is not perfect, it won't do the right thing every time but for the vast majority of CS1 and CS2 citations that have both year and date, it will do the right thing.

The code deletes year when date has what appears to be a MOS compliant date where the year portion of date matches the value in year.
