New SmartField: Last Deal Date

Would be very helpful if in addition to giving us Open Deals, Won Deals, Lost Deals count in the companies view to also give us a "Last Deal Date". This could ne a new smart field. 

I think it should be comprised of 4 Smart Fields:

1. Last Deal Date All (looks at all deal types open, won, lost) and gives you simply the latest date of last deal created
2. Last Won Deal Date. 
3. Last Lost Deal Date
4. Last Open Deal Date (currently open deal)

This would allow me to look at companies, apply filters, then show me in column which companies I have not opened deals for in say past 90 days, etc.

We run an advertising business that sells seasonal publications and we reach out to new and existing customers throughout the year over-and-over. So having ability to see a deal cadence or tempo with a field such as this would be AWESOME
