Mobile app re-do

- Changing app name - New button artwork and links using main website styling and links (General UI improvements) - Any Facebook and Twitter user improvements possible. - Change the ad server (or change to allow ads to open up on new screens) using admob - Make the 'history' scan URL's open when selected. - Have the scanned QR codes open within the app so that you can have a 'back' button to scan another code without shutting the whole thing down.
