Various cluster fixes and Unit test updates

* Updated the unit test suite to print each unit test method name we're
  running as we do so, and also with fancy colors :-)
* Added functionality to handle failed transactions, where Redis will send
  us a multi bulk length of -1.  This can happen because of an EXECABORT
  error, or because a watched key was modified during the transaction
* Initialize serialized return value to NULL to avoid segfault
* use strtol not atoi in our long response handler, to handle large values
* Fixed our return value in multi responses
* Fiexed type() command as cluster doesn't still have the '+' prefix when
  checking for what TYPE returns
* Exists should return a BOOLEAN not 1/0
* Fixed sRandMember to work in the context of a MULTI block
* Use "LINDEX" not "LGET" as "LGET" isn't a valid Redis command
* Properly set our slot for the PFCOUNT command
* Many unit test changes such that Redis and RedisCluster are happy using
  mostly the same ones.
