Improve workflow using webpack and node js

[Khaledgarbaya]

• Now we change code and we get auto compile and refresh if you do npm start.
• All js files will be bundled and minified in one file. You should remove all the global vars in the code and divide the code in seperate modules and use es6 import syntax. the Babel transpiler will do the rest.

to get all dependencies installed make sure you have nodejs installed then : npm install and voila ! you should ready to go
