Use Angular CLI instead of ngm for building

Some commands:

npm run build      - to build the library.  Output is in dist/ng2-file-upload/.
npm run test       - to run tests.  Coverage report is in coverage/ as before.
npm run demo.serve - to build demo application and serve it through browsersync
npm run start      - to run demo application using `ng serve`.  Requires the library to be built and linked first.
