Changed the ARC branch to deploy down to 10.6 instead of only 10.7 and up.

This change requires the user of the framework to set the CDEvents delegate to nil when it is no longer needed (i.e. in -dealloc).
Updated the readme to reflect the new deployment target.
Added CDEventsEventBlock type.
Added logic to use blocks instead.

- Added init* methods for blocks.

- Changed so that the old init* methods for delegates now call the new block based ones.

- Changed so that the callback executes the block.
Fix lastEvent not getting set.

- The lastEvent could some times not get set if the last event sent to the
  callback was ignored or excluded.

- Did some cleanup in the callback.
