Exif Orientation data is not copied if you use the same Uri for both Input and Output

[apinder]

This was tested on a 2.3.3 device; easy work around is to simply make sure the output URI is different from the input URI but may be causing issues related to #46.

Relevant code is
(https://github.com/brandon515/android-crop/blob/aa6023d8cb276805ec883f3eecaec4c4949007a6/lib/src/main/java/com/soundcloud/android/crop/CropImageActivity.java#L407):

       try {
            outputStream = getContentResolver().openOutputStream(saveUri);
            if (outputStream != null) {
                croppedImage.compress(Bitmap.CompressFormat.JPEG, 90, outputStream);
            }
        } catch (IOException e) {
            setResultException(e);
            Log.e("Cannot open file: " + saveUri, e);
        } finally {
            CropUtil.closeSilently(outputStream);
        }

        if (!IN_MEMORY_CROP) {
            // In-memory crop negates the rotation
            CropUtil.copyExifRotation(
                    CropUtil.getFromMediaUri(getContentResolver(), sourceUri),
                    CropUtil.getFromMediaUri(getContentResolver(), saveUri)
            );
        }

1. Output Uri gets written to by the bitmap (which is also input)
2. Exif orientations get copied from input to output
3. Exif data is lost as the bitmap has already overwritten it leaving the image with no Exif data so it's not possible to orientate the image correctly.

I'd do the fix myself but really need an IDE for this fix and it doesn't appear to be easily importable into Eclipse (I ain't savvy with Gradle and Android Dev Tools)
