Changeset 3868 in josm

move 2 files back to from styles_nodist to styles. Reason: they are listed on http://josm.openstreetmap.de/wiki/Styles as URL, like http://josm.openstreetmap.de/browser/trunk/styles/standard/elemstyles_gb.xml?format=txt. This is what some users might have in their preference file, so we cannot move it. It shouldn't be a problem to distribute these 2 files, they are pretty small.
