ADBackup 3 prerelease 2

I added all of v2 so I going to implement the app-backup bacause actually it only can configure, generate and show the app-list.

Since yesterday the easter-hollidays are ago and I go to school. So there isn't as much time as in the hollidays. So I can't upload a new (pre-)release daily and post it, but in my freetime I work on this project.

Here is the newest prerelease: ADBackup 3 prerelease 2
I moved the old 2.2 Prerelease here: ADBackup 2.2 Prerelease 2
