New attributes added to the shadow attributes

sha256, http-method, named-pipe and mutex added to the
shadow attributes. Fixing #170

This is not solving the core issue of having duplicate
attributes declaration in MISP but this is fixing the
consistency issue between attributes and shadow attributes.
Typo fixed (missing comma) between 2 attributes
