Track page views

Tracks viewing of confidential or privileged information, and adds it to the feed of database changes.

Requires config:
```
[[tracking]]
page_viewed = "Page Viewed"
```
You don't actually need or probably want this if statement here.  This is present in the ``sessionized`` decorator because it's checking to see if the method in question has a ``session`` argument.  But you probably don't care about that and want to just always log pageviews.

So you can get rid of this if statement and also the ``innermost = ...`` line which is only there to support this if statement.
