Title: Rediska_Zend_Cache_Backend_Redis, supporting tags, 'infinite life' and cleaning.

Implemented support for cache cleaning via the `Rediska_Zend_Cache_Backend_Redis` adapter.

Methods now active are:
* `getIds`
* `getTags`
* `getIdsMatchingTags`
* `getIdsNotMatchingTags`
* `getIdsMatchingAnyTags`

Added a backend options:
- __storage__
- __set_ids__ : the set name that all ids are storage
- __set_tags__ : the set name that stores the tags
- __prefix_key__ : the prefix value for all item keys
- __prefix_tag_ids__ : the key prefix value for all tag-to-id items
