Android 2.2 ("Froyo") compatibility improvements:

 - Alter a refrence to 'this' in a prototype declaration to 'TouchScroll' to aid what seem to be scope changes
 - Alter addEventListener calls to point directly to the handleEvent function as direct TouchScroll references no longer seem to work
This fixes event registration on Froyo; still tested working on iOS 4, Android 1.5 emulated, BlackBerry Torch browser, desktop WebKit
