Add columns for post/term ID, type and page for deeper analysis

[patrickrobrecht]

If one wants to evaluate the post or category viewed most often, this is quite difficult with today's database scheme as the information is not given in the database. Therefore one cannot easily differentiate between posts, categories, other archive pages and the home page.

This support request reminded me of thoughts I had when trying to implement further extensions for Statify - Extended Evaluation. At least for real-time analytics it lasts too long to calculate that on run time if the Statify table contains thousands of rows.
