29311	Ease customizing URLField validation	Arthur Pemberton	nobody	"Example  URL: ""myscheme://server/group-name/item-name""

Problem 1: `models.URLField` needs to be subclassed to change allowed `schemes`
Problem 2: `forms.URLField` needs to be subclassed to change allowed `schemes`
Problem 3: `validators.URLValidator` needs to be subclassed to change `regex` to allow `netloc` that is a hostname without a domain ad TLD

At the very least, making these changes should be documented better. The message accompanying ValidationError gives no hint as to the source issue with a URL.
