Auto fill cookies for those OJ which can submit problems on VJ by using their cookies.
VJudge Cookie Filler automatically retrieves cookies from supported online judges (OJs) so you can submit problems to Virtual Judge using your own accounts.
Currently supported OJs: Codeforces, QOJ, UVA, Luogu, and Nowcoder.
It's easy to add support for more OJs — welcome to submit PR.
When you're on a VJudge Submit page, simply click "My Account" or "Archive". The script will automatically perform — no manual steps needed.
