merging the PhotoView lib classes into sdk
Merge branch 'hotfix-observer' into feature-librum

Conflicts:
	etasdk/src/com/eTilbudsavis/etasdk/DataObserver/DataObservable.java
Trying to merge the PhotoViewAttacher, PhotoView, and IPhotoView. Probably should remove IPhotoView too, as having an interface seems like a waste
cleaned up package, need to test the photo view
Moved JavaDoc from IPhotoView to PhotoView, IPhotoView should be irrelevant now
Tweaking PhotoView to react nicely to touch events
Starting basic structure of the reader
danger!
Tweaks to the RequestFactory, and trying to get the PageflipFragment working
started working on the viewing part of the reader
got basic page flip running, need memory optimizations
performance is king
figuring out config changes

Conflicts:
	etasdk/src/com/eTilbudsavis/etasdk/Eta.java
