Setting: Customizable refresh interval for draw()

[SkepticMystic]

The breadcrumbs matrix doesn't auto refresh unless switching notes.
I can add an option for a customisable resfresh interval.

I just need to be careful about deregistering it.

setting.onChange(value => {
    plugin.interval.deregister;
    if(value && Number.isInt(value)) {
        plugin.interval = app.registerInterval(() => await matrixView.draw(), value)
    } else {
       plugin.interval.deregister()
   }
})

Should be working in 0.4.9
