Add Our Enforced Copyrights about icons

[crutchcorn]

Perfect. 👍 Thanks!

[danielhickman]

Done all edited ones for Greg Ives

[danielhickman]

Done all edited Gabe's. He still has vectors without copyright notice.

[danielhickman]

Finished Sky's. Editing his now.

[danielhickman]

We are moving to a new copyright that is easier to enforce.

Wayne's are done except future edited versions, the one's @crutchcorn edited today, and SVGs (they don't handle XMP, must be done manually for all SVGs)

[danielhickman]

Added this to Wayne's SVGs I couldn't open:

Actually SVGs exported through AI still don't have the XMP data. I feel like we have'd solid evidence regardless and will not reopen this issue.
