Lack of interest Style property group to show all asset upload forms

[Alternadiv]

It would be handy to have a style property group that has all asset upload forms from the other style properties. Seeing them all on one page would help make changes without the possibility of forgetting one. Things like page and header backgrounds are easy to locate, but there are plenty of asset upload forms "hidden" in groups and properties that we don't commonly use. To ensure you don't miss something, you'd essentially need to check every property of every group to see if there's an asset form in use.

Bonus: Throw in a blank upload form to quickly upload assets that can then be used in custom code.
