Null plugins are sad and lonely, put them with the others later Minor tweaks, force remove Plugins folder because it can prevent $INSTDIR from being deleted (assuming we're doing a standard uninstall) Rewrite version detection to search for 0.9.8 to 1.4.0 as well as future builds. Remove offending whitespace
