New crates.io versions available

TLDR: A lot of minor adds/fixes once again. Few API improvements but the most important ones are:

• Add of properties (both “normal” and children ones)
• Add of Into<str>

Now, instead of having to write:

let about_dialog = AboutDialog::new();

about_dialog.set_website(Some("https://gtk-rs.org/blog/"));
about_dialog.set_website(None);

You can write:

let about_dialog = AboutDialog::new();

about_dialog.set_website("https://gtk-rs.org/blog/"); // `Some` isn't need anymore
about_dialog.set_website(None);
