Implant web proxy support

[ItzMiracleOwO]

Migrate from #1554
(Sorry for multiple PRs, I had to resolve the conflicts)

Modified OkHttpClient to implent a web proxy method that is already wanted since #409

I only modified configs for zh and en, because I do not recognize other languages.

Thank you for your PR and sorry about the late response, there are some problems listed below that need to be addressed before this can be merged

Thanks for the reply, it has been a while before the PR has been created, please wait for me to resolve the conflicts and fix the issues.

@Vankka Hi. Please check the new codes

I probably missed something since the comments are squished together.

You still need to include the config options in all the other config files. Don't worry about translating them, you can just copy the english translation across them all.

@granny Issue resolved, please check

Just a few more things. The english translation of the comment can be changed if you think of a better way to word it.

It would probably be a good idea to add debug lines stating something along the lines of "using proxy for Discord".
