Set the network proxy settings to be used by connections started in @context.
By default %WEBKIT_NETWORK_PROXY_MODE_DEFAULT is used, which means that the
system settings will be used (g_proxy_resolver_get_default()).
If you want to override the system default settings, you can either use
%WEBKIT_NETWORK_PROXY_MODE_NO_PROXY to make sure no proxies are used at all,
or %WEBKIT_NETWORK_PROXY_MODE_CUSTOM to provide your own proxy settings.
When @proxy_mode is %WEBKIT_NETWORK_PROXY_MODE_CUSTOM @proxy_settings must be
a valid #WebKitNetworkProxySettings; otherwise, @proxy_settings must be %NULL.
