Fixed bug

If an advanced card was previously available but is no longer later,
it could crash if you had activated it earlier.
Switched to floating icon images

I think it looks a bit better
Adjusted pre-cut assets for new icon size
7: Tried switching to LinearLayout dividers

It removes some of the work but it required me to futz around with
the layouts somewhat.  Not sure how I feel about it yet but I want
to give it a shot.
