invalid consume when class properties declared without namespace attribute (with workaround)

If a variable's declared in a class and it isn't specified as public, private, protected, etc., the emitter will throw an error.

This will throw an error:

```
package test
{
   public class foo extends Object
   {    
      var bar;
   }
}
```

Here's the workaround:

```
package test
{
   public class foo extends Object
   {
      internal var bar;
   }
}
```
