Eclipse Designer -- Unable to "see" any PaperUI-created things/items

[ThomDietrich]

Right now, ESHD is the only game in town. Use the 0.8 version for now. @ThomDietrich, clearly that issue has not been fixed yet and it seems like it might be awhile. Perhaps removal of that line recommending using the nightlies should be removed until that issue gets fixed.
