BLPOP inside MULTI/EXEC block no longer crashes, instead if the list is empty the behavior is like if the timeout is reached. This fixes Issue 285

It is now possible to use authentication and DB selection options at the same time in redis-cli (Issue 298)

Fix for a race in BGSAVE that may result in some data not being saved as soon as possible (when the configured saving triggers should fire). Also known as Issue 313, more details there in the google code issue.

Fixed segfault in freeMemoryIfNeeded due to the fact that keys are now sds strings and not objects in the main hash table, thanks to Anthony Lauzon for spotting the bug and providing a patch.

redis-cli tests commented out since there is a problem with the CI server and this tests, will be activated again once the problem is fixed
