Removes global atoms dependency from emain by moving WOS to grab the
globalAtoms from window, if present. Also removes interdependency
between wshrpcutil and wps
Also adds showmenubar setting for Windows and Linux
This migrates all remaining eventbus events sent over the websocket to
use the wps interface. WPS is more flexible for registering events and
callbacks and provides support for more reliable unsubscribes and
resubscribes.
