Alternate default app grid (1/2)

Can't remember if this has ever been a part of Slim's philosophy,
but I know I always cherry-pick it in each time I build Slim for
myself...so I figured I'd at least see what you guys thought.
Functionally I haven't ever had any problems with it (been running
it over the last few of my own Slim builds).

Android 4.4 brings ListView and no more GridView and with this
some small changes was made to fit new style
