Adapter for cache storage for Redis
Extending the phpunit-version-unsupported error message

The original message did not provide any further pointers as to
what someone should do or look for, other than change their
version of phpunit (up? down?). This commit fixes that.
Made the CaptureCache cache pattern implement EventManagerAwareInterface. Also made set() trigger a set.post event which makes it possible for the user to know what the saved file name is.

Update library/Zend/Stdlib/Hydrator/ClassMethods.php

ucfirst at the previous point forces you to have lowercase first properties
whereas if you are dealing with an existing table that already has
Uppercase first, then the Hydrator wont work. The fix above maintains everything
you had before but also allows for the use of uppercase first property e.g. 
protected $FirstName;  MSSQL tables usually have this naming convention
Add trigger to 'accept' method. Remove previous changes.
