BFA (BetterFurAffinity) od xinitrc

Improves FurAffinity experience by making slight tweaks to the website.

Current changes:
* Adds orange and purple borders to "See More" images so you can easily see which posts are newer or older than the current one! (Also should be safe for colourblind folks!)
* Adds the "VX Share" button to copy a VX-version of the submission's URL
