FS#298 - Add support for memcached

http://danga.com/memcached/

It's basically a distributed key=value service. entirely In-RAM. (What happens when it fills? LRU?)

Initially, cache things that don't chagne often -- like usernames and folder names/parents but on a random photo page load, we have to hit several times.

This isn't a big deal now, but on high-traffic sites it can make quite a difference in performance.

Adding general support for this is a bit more complicated, as it would have to sit inbetween the querys and the database, so I'd rather just add it to a few hotspots as needed.

Reason for closing:  Implemented
Additional comments about closing:  There's always room for improvement, but the first parts are there. The search/folder browse improvements are a much more complex problem.

There's an official PHP extension -- php-pecl-memcache.

We could also use it to store session info.

-devel now allows one to specify a memcache session handler, or one can just use the default PHP stuff which of course can be memcache.

the default config file now includes a memcache example. I have it running on the peachy photography site, and it rocks.

Initial candidates for caching:
*) userid -> info [un,fn,ln] (called once per page and almost never changes)
*) folderid -> info (and/or 'get_path_to_folder' cache)
*) albumid -> info (and/or 'get_path_to_album' cache)
*) photoid -> keywords
*) photoid -> tech_info

Then:

*) Search results -- the search query return everything, and it gets cached for a short time. we page back and forth from the cache.
