Upgrade syntax for JsLIGO decorators

Christian Rinderknecht requested to merge rinderknecht@decorators into dev

Motivation and Context

Decorators in JsLIGO now follow the official format: @foo or @foo("bar"), instead of the ad hoc format we used until now: // @foo and // @foo bar. Only predefined decorators are allowed now.
