Improved the '!=' and '==' operators. Now, they can compare objects of different types. e.g.: "string" != nil;
Added a make method for the Array object. 'Array.make(10,false)' creates an array with ten false boolean values.
Improved the Parser. Now it can skip some bad characters an can continue. e.g.: '@2+4' is a valid code, but will produce an warning.
