DrupalGap Drupal 8 PSR-4

This is a quick update for current module structure.

I think we need to start creating new issues with tasks for the D8 version.

Anyway while I'm trying to understand how D7 version works I have a few questions...

For example we don't need (AFAIK) to verify the token generated by services for the D8 version. This is because we can do this:

\Drupal::csrfToken()->get()

So we don't need this feature. right?

@tyler I'm not sure that we need basic_auth. I think that "rest" and "views" for sure.

Thanks guys!
