forked from len0rd/rockbox
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24272 a1c6a512-1295-4272-9138-f99709370657
