Missing arguments after GlobalMenu execution (issue #868) (#871)

* Install.__init__ parameter kernel as a list everywhere.
I've dropped the string check, as it shouldn't happen again, and it's good that it fails, when it happens

* Global Menu now loads in the arguments dict all options enabled with default value and no manually selected (issue #868)
