[FEAT] Diff of graph implemented. TODO: change colors in Graph Explorer. Instead of yellow -> red : blue -> red.

tidying all libs ('js' dir renamed to 'lib' because of new package-based hierarchy which mixes filetypes) and refs to them from the templates etc

Tidying annotations: moving all app's libs => to project static libs (no more npm/bower install, just static files now)
