[feature request] sync remote hosts file

[jhdxr]

Is there any plan to support to download remote file like what adblock does. We can make use of the existing comment rules.

for example:

#remote(http://10.0.0.101/shared)

means sync the whole local hosts with http://10.0.0.101/shared

and of course this applys to group

#==== project1 #remote(http://10.0.0.101/project1)
#====

it's easy to co-exist with other rules

#hide remote(http://10.0.0.101/shared)

use space or something else as separator, and each comment represent a single rule.

btw, we can use the comment to save more info if needed, like #lastupdate(2016-04-26 12:00:00).
