[MG] Crossforum geomap - scoping and navigation

I taught the geomap some new tricks:

 1. Zoom in using the (+) at top left.  Note that the feed slows down.
    It only shows bites that have geolocals in the current viewport.

 2. Pan by grabbing the map and sliding it around.  Note that the
    content of the feed changes with each pan.  It refilters itself to
    match the area that's currently viewed.  (This becomes clearer as
    you zoom in further.)

 3. Press the back button.  Navigation is now geared to the pan/zoom
    controls, so you can revisit previous areas.  Each area is
    bookmarkable from the address bar, too.

 4. Switch to a different base layer using the (+) at top right.  Note
    that the layer controls are independent of the navigation and
    pan/zoom controls.  So you can revisit previous screens using the
    back/forth buttons, even while switching layers.

    Layers aren't bookmarkable, if we keep it this way.

It could be slow on some set-ups.  There might be bugs, please say if
you see any,
