Net! Socket & Server classes updated (major changes)

Hello,

Sorry, again a PR, but I prefer sending a PR for this changes, because some functions disappears, some appears, new data types. I don't know how were these classes before in node api, so, I don't know if that's functions & overload were wanted (for a weird reason) or if they were just outdated.

Note : "connections" param in js.node.net.Server is deprecated
