Added some minor improvements

Well, I like this project and want to support it.
I've fixed some minor issues and added some code. For example, in many files, spaces and tabs were mixed. I changed this to only use tabs. For more details, you can see the commits. :)
I also updated iScroll and I had to add code to viewNavigator, because there was a "bug" with that version.
