add proxy support

[parkouss]

It would be really nice to have support for proxies, I need to investigate a bit on how to do that. But webmacs is mainly using qnetworkmanager, and I guess there is some code built in Qt for that. Probably there is only glue code required to add the support.

@FirstLoveLife could you try by setting the global environment variables http_proxy and https_proxy?
export http_proxy=socks5://host:port
export https_proxy=socks5://host:port

It might work out of the box, though dns requests won't be proxied I think.

I have git pull, activated the two lines in .zshrc and source it just now. But still cannot connect to google.com.

ok, thanks - could you try with the branch "proxy" please (PR #62) ?

Please set the following in your config file:

from webmacs import variables
variables.set("proxy", "socks5://host:port")
variables.set("proxy-dns-requests", True)

And tell me if that works. Note that you should also be able to use the system env var - in such case you only have to define the proxy-dns-requests variable.

Sorry for the late reply(I was busy recently)

I have put the three lines you gave into ~/webmacs/init/__init__.py, but still cannot connect to google(only white background occurs)

(venv) ~/dev/webmacs >>> python -m webmacs.main                                                                                                                                           ±[●●][proxy]

Hmm. Is it working for you with qutebrowser, with the webengine backend? If yes, with which config options?
