investigate switching from bower to npm

[bartvde]

We use gulp bower files package which results in this files array for the build:

[ '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/jquery/dist/jquery.js',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/less/bootstrap.less',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/dist/css/bootstrap.css',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/dist/js/bootstrap.js',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/dist/fonts/glyphicons-halflings-regular.eot',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/dist/fonts/glyphicons-halflings-regular.svg',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/dist/fonts/glyphicons-halflings-regular.ttf',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/bootstrap/dist/fonts/glyphicons-halflings-regular.woff',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/jquery-ui/jquery-ui.js',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/d3/d3.js',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/font-awesome/css/font-awesome.css',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/font-awesome/fonts/FontAwesome.otf',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/font-awesome/fonts/fontawesome-webfont.eot',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/font-awesome/fonts/fontawesome-webfont.svg',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/font-awesome/fonts/fontawesome-webfont.ttf',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/font-awesome/fonts/fontawesome-webfont.woff',
  '/Users/bartvandeneijnden/opengeo/git/wps-gui/components/jsonix/dist/Jsonix-all.js' ]

However some of these scripts (such as jquery-ui.js) will not be present when installed via npm and the git repo.
