Release of Version 4.9.2

Instead of hard-coding a check for pinned items when storing the first
item, allows the creater of NodeIterator to specify how the comparison
should be made.

This also allows storing the newest post (whatever it's status is),
instead of simply storing the newst non-pinned post, which prevents
redownloads in case a user adds only a pinned post between runs.
