* Fix Importer emailformat
Str::slug() strips periods from the string, which caused our existing
logic to misbehave when generating a user's email on an import. Adjust
logic to use generateEmail() helper on user instead. Also clean up some
of the logic in this method.
* Remove dead code.
* More refactor/cleanup of the user create method. I think it is almost readable now.
