Support auto Initialize comments for oldder articles

[giscafer]

blog owner didn't want to manually Initialize comments for every articles after change the comments system to gitment.

So, we want a easy way to Initialize comments for all articles by once time

That's a good suggestion, though I've initialized all the old articles manually
