Add Fullscreen Offsets to BladeView

[michael-hawker]

When the BladeView is in Fullscreen mode, it's hard for a user to tell they can scroll with the new collapsing scrollbars:

(e.g. there's blades to the left I can scroll to here.)

It'd be great if we had a FullscreenMargin or FullscreenLeftOffset/FullscreenRightOffset properties to allow for the edges of previous/next blades to be shown:

<controls:BladeView 
    BladeMode="Fullscreen"
    FullscreenLeftOffset="50"
    FullscreenRightOffset="10">

Was just thinking too, that we could add a 'snap' property and use the leftoffset in either mode too.

Does the FlipView offer such properties?

Whats the status? Can we archive/close it?
