Runelite: 2010 interface close button inconsistency

[Pupper3]

When hovering over the close button in the skill guides, the button is replaced by the new sprite temporarily.

All of the close buttons are untouched except for the logout button in resize-able and the skill guides.

@raqes this is just sprite 541, should be a simple fix

Need to find the 541 image, dont know if anyone has it?

I got the image and fixed it locally, I'll make a PR once I get home.
