Vaadin Flow 2.0.0.alpha4

2.0 version of Flow will bring the possibility to use Polymer 3, npm and JavaScript Modules
instead of Polymer 2, Bower and HTML Imports.

Among other fixes since alpha3, alpha4 comes with bug fixes, improvements and better development experience.

Flow 2.0 requires that in addition to Java 8 and Maven you have node.js + npm installed.
