[Rules] Editing hosts file locally

[roviury]

I think it is better to give users to add rules using local text. In each rule in the [rules] tab text editor: @[server1] google.com @[server2] yahoo.com @[server1] apple.com

in the [servers] there are server1 = 111.222.333.444:53; server2 = 101.210.300.405:53

when the texts in [rules] are edited/re-saved, @[xxxx] get converted to the address internally. (and also check it)

if the text cannot be converted, it cannot be saved. (e.g. no server1 in [servers])

In such a way, users no need to assign urls to download hosts file. and they can easily edit it. If the server hosts are dead, it can easy to change the host addresses.
