jpeg,png: Merge user interface code and plugin entry point of the two plugins (part of FS#6321).

* Created new directory, imageviewer/ and moved both jpeg/ and png/ under it.
- this still doesn't merge the two plugins. i.e. both jpeg.rock and png.rock will be made for color targets.
- I'm thinking to merge the two plugins to single image viewer later.
