------------------
* Common operators (e.g. `+`, `>`, `==`) now call into highly efficient built-in implementations for standard types
(i.e. `INT`, `FLOAT`, `bool`, `char`, `()` and some `String`) if not overridden by a registered function.
(i.e. `INT`, `FLOAT`, `bool`, `char`, `()` and `ImmutableString`) if not overridden by a registered function.
This yields a 5-10% speed benefit depending on script operator usage. Scripts running tight loops will see
significant speed-up.
* Common assignment operators (e.g. `+=`, `%=`) now call into highly efficient built-in implementations for
standard types (i.e. `INT`, `FLOAT`, `bool`, `char`, `()` and `ImmutableString`) if not overridden by a registered function.
* Implementations of common operators for standard types are removed from the `ArithmeticPackage` and `LogicPackage`
(and therefore the `CorePackage`) because they are now always available, even under `Engine::new_raw`.
* Operator-assignment statements (e.g. `+=`) are now handled directly and much faster.
