Adds reverse search links above imeji.

Settings: The script now has settings to enable/disable services, available through your userscript extension.
While on 8chan, click the userscript extension's icon in your browser toolbar and you should see the "Settings" button below the userscript.

Services:

  • pixiv: if the filename matches their pattern
  • iqdb: hidden form upload
  • saucenao: hidden form upload
  • ascii2d: postMessage across tabs
  • trace.moe: postMessage across tabs
  • google: litterbox upload

Note:
8chan.moe prevents hotlinking so passing the image URL to reverse search engines will result in errors.
For IQDB and SauceNao, a hidden form is created and the image uploaded cross-site, this works because their upload forms do not use a unique token.
For ascii2d and trace.moe, the image is sent across browser tabs using postMessage because they use a unique token.
For google, the image is uploaded to litterbox and then passed via URL because they do have unique tokens and Cross-Origin-Opener-Policy preventing postMessage.
