Send impl for tty::windows::Console

[hayd]

I am seeing the following error on Windows (but not on osx/linux, these both work), here DenoRepl is a struct containing an Editor<()>.

error[E0277]: `*mut std::ffi::c_void` cannot be sent between threads safely

I'm not sure why this is. Is it because Console doesn't implement Send?

A workaround: piscisaureus/deno@02b8202
Should this be incorporated into rustyline?

I think this is fixed by #161.
