Allow Date Fields to have a locale for date parsing

Currently if somebody uses a date format that is locale dependend
date fields can only parse a single format depending on the nodes
host locale. This can cause lots of problems since nodes might have
different locales. ie. "E, d MMM yyyy HH:mm:ss Z" where you have
"Wed, 06 Dec 2000 02:55:00 -0800" for en_EN while
"Mi, 06 Dez 2000 02:55:00 -0800" for de_DE.
