Alarm picker: Fix position for iPhone 5

The y-position was hardcoded for iPhone 3 and 4 and thus did
not work for the iPhone 5.
Alarm text: Make instructions more succinct
WebView: Removed the "scale to fit" option

This makes webpages look much nicer. However, images need to be
resized and the full version of the website do not look good!
xcode: update xcode project files

not sure if i need these but doing it anyways
