Filestore Cache Expires_in Plugin

Adds a :expires_in option to Rails filestore caching, in line with memcached store. Providing a very easy way to add high capacity caching to a site.

Model observers and sweepers are still useable as well, of course.

Filestore caching is a much easier method of caching to implement quickly than memcached, since it just involves writing the cache data to files in the tmp/ directory (also making it good for shared hosting environments).
