[ic] Ads extenstion first version done

[Mike Heins]

As requested and funded by some of our kind Interchange users, I have
put up the ad serving extension to Interchange.

   http://www.perusion.com/contrib/ads-0.01.tar.gz

There is an INSTALL document and rudimentary documentation in README.
I have tested it fully on MySQL. It does not yet work on Postgres because
it relies on AUTO_INCREMENT fields -- this can be addressed if extra
time is found.

If you said you would contribute a half-hour, you are asked to follow this
link to pay by credit card:

    https://www.perusion.com/c/public/ord/checkout?mv_action=refresh&mv_order_item=misc-0001&mv_order_quantity=75

       or

Click twice to pay for one hour (if anyone said they would contribute that).

The more payment, the more time I will have to add features like:

	-- Ad start/expiration dates
	-- Expire by number of exposures
	-- Expire by number of clicks
	-- etc.

I expect to put this extension in the distribution for 5.4.
