Ensembl Memcached integration
Memcached is a distributed memory object caching system.
We are using memcached to speed up website by caching lots of things in EnsEMBL, such as paths to pluggable static files, semi-static rendered html pages, generated images, image-maps, some database query results and a lot more.

Major idea of this modification is to be able to apply tags for the items stored in memory, so that there's a way to delete lots of items at once by tags.
tag_add tag key - adds tag for the key
tag_delete tag - deletes all keys with given tag
tags_delete tag1 tag2 ... - deletes keys which have all given tags
