Need support for smaller viewheights + certain phones

[phillipson808]

The content bleeds off the screen into whitespace if the vertical size of the screen is shortened.

talked to @phillipson808 about this, but we can use overflow: scroll on the top-level panel component classes, e.g. .Burst, .Settings, etc.

Also, for some of the components the bottom most element may need some bottom padding, e.g. on the <Burst /> component, the .Burst-button could change margin-top: 10px; to margin: 10px auto; to add a little space below when the window height is less than the component's total height.

@alissarenz - would it make sense to include other issue's that are small css fixes here as well? issue #40 (Align Oversample checkbox) for example?

It might make sense to include viewwidth adjustments here too, particularly for the preview component - on the old iPhone 5/SE & Galaxy S5 the .Preview > .Frame div runs off the sides, we could scale down the height and width to fit here, seems to be aligned with the goal of this issue

I'll check on responsiveness and fix what I can
