Add support for show and hide cursor?

[DevinR528]

Would a pull request to add the ability to hide/show the cursor be welcome, something like this?

impl Term {
	...
	fn cursor_hide(&mut self) -> io::Result<()> {
        let esc = "\u{001B}";
        let hide = format!("{}[?25l", esc);
        self.write(hide.as_bytes())?;
        Ok(())
    }

    fn cursor_show(&mut self) -> io::Result<()> {
        let esc = "\u{001B}";
        let show = format!("{}[0H{}[0J{}[?25h", esc, esc, esc);
        self.write(show.as_bytes())?;
        Ok(())
    }
}

Sorry to conform to how your internal design is it would make more sense for hide and show to be implemented in common_term.rs:

pub fn show_cursor(out: &Term) -> io::Result<()> {
	let esc = "\u{001B}";
    out.write_str(&format!("{}[0H{}[0J{}[?25h", esc, esc, esc))
}
and so on...

then just call the func in the Term method
this does work on both windows and linux. Hope this is helpful, thanks for a great lib!

This is implemented now.
