Stats v2 proposal - for Thursday's meeting

Enclosed is my stats v2 proposal, as it stands today.
Things to note:

- Using the dictionary *grammar* to describe objects, without making 
dictionary *objects* (since that's impossible to implement due to some 
WebKit limitations).
- Using an unique "id" to point between different objects inside the 
stats DB.
- Focusing on the objects that need defining, expecting to fill in the 
stats references later.

I think this looks cleaner. It's obvious (to me, at least) where to add 
the stats that aren't included yet.
It's only 6 pages, including the introduction and a code example.

Comments welcome - more on Thursday!
