1. Fix != operator definition …

   Problem: If a class declare the not-equal operator `!=`, the parsing
   is wrong. For instance, the folowing program:
   
   class A
     def !=(other); end
   end
   
   is parsed as if the method `!` was a defined with the body expression
   syntax leading to the following tree:
   
   (program [0, 0] - [3, 0]
     (class [0, 0] - [1, 20]
       name: (constant [0, 6] - [0, 7])
       body: (body_statement [1, 2] - [1, 16]
         (method [1, 2] - [1, 15]
           name: (operator [1, 6] - [1, 7])
           body: (parenthesized_statements [1, 8] - [1, 15]
             (identifier [1, 9] - [1, 14])))))
     (identifier [2, 0] - [2, 3]))
   
   Solution: Declare `!=` as a possible operator definition.
