Strip XMP Packet from the end of binary image data

[Tom Glod]

Scratch taht, its the modified date timestamp that changes.

I will try using regex to get the ID and check it to see if the clipboard
image really changed or not.

should be a safer and quicker workaround...I think all adobe software does
this when copying to clipboard.
