Allow date fields to ignore browser localization

[edalzell]

In my Events addon, you create an event that has a timezone, a date and start/end times. Each of those is a separate field to handle all of different types of events (single, recurring, multi-day, etc). We need a separate timezone as you may be entering events not in your own times. In those cases we need the date to NOT be localized based on the browser, so that it looks the same for all CP users.

To handle this, I'd love a field config for the date field that disabled browser localization.
