avoid NPE when scaletype is called in constructor of ImageView
delegate onlongclicklistener to attacher
Remove log spamming without changing source (hardcoded DEBUG flag) and
without using Proguard to remove the log entries.

Both of these techniques will still work, if desired.

New setScale() method with various options. Deprecates the zoomTo() method.

Update library/src/uk/co/senab/photoview/PhotoViewAttacher.java

fix  ImageView no longer exists. You should not use this PhotoViewAttacher any more.
the cleanup don't work so i fixed it like this.
don't keep the ViewObserver as it may not be alive when we need to remove our view
(otherwise it crashes when the PhotoView is in a Fragment in a ViewPager and the page is no longer kept)
