[Blake Rouse]

Make url field on BootSource unique.

[Blake Rouse (blake-rouse)]

For some reason the diff is not showing the addition of "unique=true" on the url field in the BootSource model. It is there in the branch, must have to do with me removing it from the prerequisite and adding it to this one.

[Gavin Panella (allenap)]

Looks good.
