Add trait support

[davidbcn]

Mostly I found that support for traits is a little bit crippled.

[1] Autocomplete when adding trait to class does not populate with traits in the same namespace. You need to use full namespace ("\Drupal\fdf\MyCustomTrait" instead of "MyCustomTrait" directly).

[2] Autocomplete when adding traits will let you use anything, including interfaces and classes. It should only populate with traits and show error when "using" inside a class is pointing to something that is not a trait.

[3] Methods "inherited" by a class through a trait are not seen by Intellisense. I had to resort to creating stub interfaces for Intellisense to pick the methods in the traits.

It would be great to see support for traits improved.

UPDATE: Looks like some of the issues are due to the fact that PHP Tools needs use statement in trait to have full namespace.

Hi David,

Thanks for the feedback. We've fixed [1] and [2]. So these will be in next update.

We'll improve other traits features in a future updates as well.

Best,
