Integrates Electron + Improvements/Fixes

[sean-perkins]

Bug Fixes

• Resolves symlink script not working on Windows

Features

• Implements Electron
• Extends symlink script to handle extensions

Electron Process

• Symlink the main app folders into an electron folder
• Extend build process to target .desktop, similar to .tns for {N}
• Task hooks to replace: moduleId: module.id references that conflict with Electron
• Uses AngularCLI's multiple app syntax, to build a webpack build using all standard tooling
• Injects electron run script into the dist directory after it's built
• Launches the electron task via npm (doesn't require global install of electron)

Note: This is just the first stab at getting electron integrated. Still need to integrate custom build tasks for: linux, windows, mac, etc.

We should take the opportunity with this PR to add post install scripts from root that installs the nativescript and electron project libraries as well.

+1 FWIW... electron support would be amazing.
