Fixed NullPointerException when editing usernames/passwords for the first time on some devices
Guard against NullPointerException which has occurred at least once in the wild (not sure how, though)
Converted tabs to spaces
Updated version number to 1.1.1 and updated release notes
APK for v1.1.1
Don't try to download AVXW, CRooked, and Crossword Nation by default if the user hasn't set a preference yet (in which case they certainly haven't entered a username and password)
Added fast scrolling to puzzle list, using https://github.com/nolanlawson/CustomFastScrollViewDemo
