  • Update Frame selector options

Known Issues:

• Hovering over an avatar in a tooltip will generate another tooltip - this has been temporarily worked around by disabling tooltips on avatars, but of course they work as usual on usernames
• The frame selector in the admin panel's user editor is broken, but the other ones (username, title, postbit, profile) work fine

• "Neon Gradient" and "Pokeball" frames are broken in frame preview
• Square avatars are now connected to the "Disable Frame Styles" button, meaning they're no longer forced just from having the addon active
• Admin Panel: Add option to control Postbit dim opacity
