…om camera - Android

- saveToPhotoAlbum feature fixed by taken into count content - uri. (writeUncompressedImage method) ( see: apache#611 (comment) )
- make saveToPhotoAlbum future proof by using the MediaStore to insert the taken image
- made a method to calculate the compressFormat based on the encodingType (JPEG or PNG)
- layout of the performCrop method is adjusted
- removed unused rotate variable inside processResultFromGallery method
