No support for @SupressWarnings

[psaraviaq]

Unused variables are still underlined even when SupressWarnings is applied. This did not happen when working with the RedHat extension.

@SuppressWarnings("unused")
public class Abstraction {

    public static void main(String[] args) {
        Object object = new Object();
    }
}

Findings from my testing:

1. @SuppressWarnings("unused") really is ignored, while others, like @SuppressWarnings("static-access") are correctly honored.
2. Unlike the Red Hat extension, this one doesn't seem to supply Quick Fix for adding/extending @SuppressWarnings for any type of suppressible problem.
