Multi Url Picker datatype isnt flexible enough

[drummerboy46]

We have a continuing issue with our content editors where they copy and paste a raw absolute URL for internal site content into the link box of a Multi URL picker instead of picking (or searching) for the content in the tree. The difference between the two for the editor is pure convenience, but the repercussions in content management means that unpublished content isn't tracked and you end up with 404's instead of content being gracefully removed (for nice things like content panels).

I think it would make a lot of sense to extend the datatype to include the following...

turn on/off the external link field
turn on/off the querystring field (already implemented, but not sure if querystrings work with internal content & media links)
turn on/off internal content picker
turn on/off internal media picker.

The url picker should be flexible enough to limit to a single URL "type" or a combination (or all) of the above.
