Separate cross-shaped pupils from +_+

Posted under Tags

The bulk update request #11014 has been approved by @evazion.

remove alias cross-shaped_pupils -> +_+

Previously discussed in topic #18043, + + currently conflates the starry-eyed look of excitement/joy(post #5462697, post #81802) with characters who just have naturally cross-shaped pupils(post #123047, post #2026703), some of which look like the former, while others look nothing alike.

There are actually a lot of very similar, but still recognizably distinct things in + + that may deserve their own tags, but most of them still fit under + + or cross-shaped pupils, so I think we should at least separate these two tags before we start worrying about how granularly we want to take things.
