 Make sure uploaded images are oriented the right way.

 When using a mobile device to set an avatar or a cover image, there are
 cases when the image can be saved upside down. We need to check the exif
 Orientation of uploaded images and rotate them if needed.

 Introduce 2 new methods into the `BP_Attachment` class:
 - `BP_Attachment->get_image_data()` to get an array of all image datas
 (including exif datas)
 - `BP_Attachment->edit_image()` to edit the image orientation and/or
 resize the image.

 Use these two new methods within the `BP_Attachment_Avatar->shrink()` and
 `BP_Attachment_Cover_Image()->fit()` methods.

 Finally include a unit test for the `BP_Attachment->get_image_data()`
 method to check we get the orientation meta for all supported WorPress
 versions.
