Background control returns repeat-all instead of repeat

[cgrant992]

Issue description:

Like the title says, the background control returns 'repeat-all' for the background repeat property. Not an issue but just figured it should be changed to 'repeat' just so no logic is required when trying to output it for CSS.

Version used:

(Did you try using the develop branch from github? There's a chance your issue has already been adressed there)

Using theme_mods or options?
