fix dataexplorer datepicker (works best in chrome)
replace deprecated singletons with spring components, rename app. to org.molgenis. to enable detection by spring component scan
rename WebAppUtil to ApplicationUtil (doesn't require a web app, command line app is also ok)
remove deprecated DatabaseFactory (use DatabaseUtil)
