commit 5e3a54f92a593f916bbf893409b72ff23faa1827
Author: Renat Akhmerov <renat.akhmerov@gmail.com>

    Update git submodules
    
    * Update mistral from branch 'master'
      - Remove a TODO comment about saving an action spec
    
        * It's clear now that we don't have to store an action specification
          as part of the corresponding action execution object because
          the notion of action specification itself is specific for a certain
          type of action. In our case, ad-hoc actions.
          All changes recently made in the Mistral layers above the engine
          prove the correctnes of this thought. The comment can be safely
          deleted.
