Implement dynamic typed definition arguments

[JoaaoVerona]

Right now, definitions must specify their arguments types. For example:

def print(string name, int age, any message)

Although any can be used for specifying any type as valid, it would be further better to not require any type - so it would be evaluated to any -, making it optional. For example:

def print(string name, int age, message)

Or:

def print(name, age, message)

Things to note:

• Overloading of definitions. What will happen?
• Container::findFunction. How to properly find functions when there is overloaded definitions, and some/one of them could contain 'any' as argument type?
