vuze NPE fix on startup
first attempts to make sure promos look the same on all phones, no padding on the sides
cleanup, warning
just hard coded the promotion aspect ratio. tried several async ways of getting the bitmap but then couldn't refresh the image view on the grid on post load, and picasso doesnt support a resize(width,-1) [with just one dimension]
no longer loses the first image, maybe this would help trying to get the ratio dynamically
I now understand gridview's like the palm of my hand.

Promotions are now displayed using the entire screen across all devices, smoothly.
