Sleazy Fork

Please support for `hentaienvy.com` and `hentaiera.com`.
These are sister sites of `imhentai.xxx` and `hentaizap.com`, so I think it should be easy to support them.

I use this script all the time, so thank you for creating this useful script.

Support has been updated.

By the way, thank you for reminding me that these four are sister sites. Now the script can use the same code to support all of them.
