Rename overloaded operators (add underscores)

Browse source 
* add suffix unary operators
* add _! operator
* _._ and _&_ operator overloading
* allow calling function references with _! and access variables with _._
* rename . method operator to !
* various cleaning & improvements

Documentation will follow at some point.
