Tag alias: /gs -> genderswap

Tag alias: /gs -> genderswap

Shortcut for a popular tag.

1. genderswap is already short enough

2. /gs could be

• gyakuten_saiban
• gundam_seed
• gundam_sentinel
• gensou_suikoden
• gokujou_seitokai
• golden_sun
• gedo_senki
• guin_saga
• gakuen_shinsengumi

and many characters

3. Use "Danbooru Uploader"'s tag autocompletion

Agreed, too short. Focus on longer tags, especially ones with multiple words or punctuation that's annoying to type.
