Apply some minor changes to the helm module
Apply some minor changes to the helm module

Remove usage of the following variables, since they are no longer
present in helm's source code:

helm-M-x-fuzzy-match
helm-completion-in-region-fuzzy-match

Also remove the usage of the deprecated helm-mode-fuzzy-match variable.
Instead, modify completing-styles so that helmized commands will use
multi- or fuzzy-matching, respectively.
