Updated the dataset view for image functionality.
The Image view now displayes the images in each individual set, enabling multi sets of images or previews on a page to be used by the ImageView.
Functionality also added includes:
- A Play and Stop, to cycle throught the set.
- Resizing of the widget based upon the image size - This could be changed in the future to prevent moving of buttons (functionality).
- Ability to show image properties such as Timestamps, Filesize and Dimensions (of preview image, not the full size. a TODO for future updates).
Updated the ImageView such that the "Play" function now works with a play speed - this is intended to allow a "slideshow" sort of presentation. The ImageView window will not resize to anything smaller while the play function is running, this could be updated to include when the play function isn't running too. Intent of this is to allow users to easily access the buttons to "stop" etc, without them shifting too much. This is likely only a temporary fix.
Renamed files/app to more appropiately represent function/purpose.
Was called Matts_view, now called slideshow_view
Fixed up a couple of bugs, including the download link and removing the "comment" secion from view, untill has been properly implimented in the future.
