Custom Field: Date

Maybe this should be built into the stock default fields instead of it having to be a custom field, but with every asset we have a purchase date, or acquired date.  Currently, we have to create that as a dumb text field, allowing anyone to put the date in any format they choose.  Would be very beneficial to have either a "Purchased/Acquired Date" as part of the default Asset form, or the ability to create a custom field type as Date that would have a date picker associated with it, controlling the date format.

Then, likewise, would be super beneficial to be able to search for all assets purchased before X date as part of the advanced search.
