Fix bug 11274. Don't hold a lock on projectInfoMap for so long, fetching interesting mmp/bld.inf/etc list outside the lock instead. Add a temporary resource listener just in case resources are modified when we're not looking (I never saw this fire).

source.uidesigner.jar = src/
output.uidesigner.jar = bin/
bin.includes = plugin.xml,\
               uidesigner.jar,\
               META-INF/MANIFEST.MF,\
               plugin.properties,\
               icons/
