New sites to filter from copycats_removal.goggle

The following sites appear to be StackOverflow copies:

```
http://www.javawenti.com
https://codehunter.cc
```

e.g. See:

http://www.javawenti.com/?post=297274
https://codehunter.cc/a/git/how-to-perform-case-insensitive-diff-in-git

Open copycats_removal.goggle and review the existing filtering entries. Add javawenti.com and codehunter.cc consistently with the current rules, then verify that both listed sites are covered by the filter. The issue's linked examples provide URLs to check against the intended sites.
