Add content blocking proxy settings

[ameshkov]

We're going to add the proxy module in v0.102:
#391

Here's the necessary minimum that should be configurable:

• Enable/disable
• Filter lists (consider extending /#filters)
• Certificate (we should generate it by ourselves, we should allow users to download this cert)
• Port, network interface
• Proxy authentication
• Proxy types: HTTP, HTTP over TLS

Not at first. But in the future -- of course, we'll add both of these options.

@ameshkov is this issue include about add separate pages for place cosmetic filtering rules lists?

@Archivebase yeah, I guess we can use either this one or #391

Support for socks5 proxy is very important. Thanks a lot.
