Reorganize ENet wrapper. Loading is now explicit like in other GFM wrappers.
Removal of the possibility to "let the GC release resource". The current GC might call destructors but this is not guaranteed.
Syntax and formatting to marche GFM style.
[ENet wrapper] Address is now a value-type.
Remove calls to destroy() instead of close().
Remove enums that replicate ENet enums. Imho they add very little value against the values from the wrapped library.
