Brandon Jordan 4321a7def1 Base+Userland: Add menu item icons 
Base+Userland: Add menu item icons

This adds missing icons to Presenter Presentation menu.

This adds missing icon to Image Viewer View menu.

This adds a scale icon for the Image Viewer and Font Editor.

This moves the Fit Image to View icon to the 16x16 folder as it's now
used by Image Viewer and not only Pixel Paint.

This improves the fullscreen and play icons so that they fit together
better.
