Bug 140839

I think the only way to solve this for all cases is to parse the entire source file for every anonymous function entry
in the call stack.  I've made a change that works, except in these cases:

a) The anonymous function with an assigned name has its first line of source on the line where the assignment occurs,
e.g. "aMethod : function() { var x = 0".  In this case, the function name will be displayed as 'anonymous'.

b) The function is anonymous but is enclosed by a named function that is assigned up to several lines before the start
of the anonymous function. For example, in this example the anonymous function will be incorrectly displayed as
"aMethod" instead of "anonymous":

aMethod : function() {
  function() {
    var x = 0;
  }.apply(this);
}
