Remove the `TTTPrepareBlockSelf` macro, in favor of `EEEPrepareBlockSelf`

The new macro resides in epologee/EEEOperationCenter and has a two-step setup to prevent deallocation of `self` during the execution and use of the blockSelf/weakSelf variables. Removing the TTTPrepareBlockSelf macro will force you to re-implement the two-step method manually, but it's a step towards a better future...
Bump the version, after `pod lib lint` passes.
