changelog
manually reconnect the connection in the PubSub class. This avoids blowing out the stack. Fixes #179 and #195.
added the ECHO command for completeness
use response callbacks for sort() with tuples to work with pipelines
add a debug_object command - so we can get a key's size (among other things)
Added __del__ methods for classes that hold on to resources that need to be cleaned up. This should prevent resource leakage when these objects leave scope due to misuse or unhandled exceptions.
