Show version info

I see that my easylist.txt contains this line:

! Version: 201412102340

It would be nice if the page at luakit://adblock included that version string.

Ok, clear to see it's informative, so we could include this info.
Moreover, my next tasks on adblock are auto-updates and URI-driven
AdBlock subscriptions management.
I keep this feature request in my mind, will be good to implement it in
several days.
