Tag alias: _summer -> summer (eroge)

Tag alias: _summer -> summer (eroge)

The name is just a suggestion. I'd accept any other good name.

Reasons for the alias:

• The initial underline does not appear at the list of tags of a post anyway, so it looks the same as summer. It is confusing.
• And the tag _summer looks misplaced in the alphabetical order, because in the list of tags it starts with "s" (not with "_s") but appears before "a".

Example of tagged post:

• post #192778.

Alias it to underbar_summer, as that's actually how it's prononuced.

Well, it's read as "Underbar Summer" so maybe the tag should be underbar_summer?

Edit: too slow

If we could display the underscore I'd totally leave it as is, but since we can't, yeah, aliased to underbar_summer.
