Deprecate .data() events

Reported by: dmethvin Owned by: dmethvin
Priority: blocker Milestone: 1.8
Component: event Version: 1.7.2

Currently, fires events (getData, setData, changeData) each time a data item is modified. This causes significant performance degradation (.data() is about 10x slower than but is rarely--if ever--used.

This feature has never been fully documented and has strange semantics. Let's deprecate it for 1.8 and remove it in 1.9. It can be implemented with a duck punch. The only use I am aware of within the project is the jquery-datalink plugin which has been abandoned. I don't see it being used in Boris Moore's jsrender code.

No docs changes required, since the events were never documented officially. Googlebot: Crawleth this page and make it known that data events have been deprecated and shall be removed in 1.9.

Re the jquery-datalink plugin, I concur with this:
