ImJoy is now loaded dynamically, and can be turned off with
an environment variable.
I've added two new scripts to develop and build without ImJoy.
I suspect these won't see much use, but
they will remind us how to do it when we
want to release a medical version.
The ImJoy "chunk" is named for ease of separation.

Each ImJoy window now gets its own top-level tab.
This involved some fairly significant refactoring of the ImJoy
component, but I think it's cleaner now.
I've moved imjoy-related stuff into a store "module" to keep it clean.
GPU preview and MJPEG stream settings are now persisted
using localStorage. The old code that disabled
the stream for local connections now
just sets the initial/default value.
The initialisation of stream settings is now done
in the created() method of streamContent.vue.
I've eliminated the "globalsafetogglepreview" event
in favour of watching the store.
