Update winit to 0.13.1

[branan]

Winit 0.13.0 has some fixes for window management on X11 that avoid some messy behavior with Vulkan surfaces (see rust-windowing/winit#434).

[branan]

It might be worthwhile to hold off on this until rust-windowing/winit#484 is merged and released. Vulkano could then pin to 0.13.1 in order to avoid its users having to manually run cargo update for x11-dl 0.17.5

[branan]

Updated this to point to Winit 0.13.1 to pull in the x11-dl dependency fix

winit 0.14.0 is out now. No other changes should be required to increase this to 0.14.0.

cocoa should probably be changed to version 0.14 though, since that's the version winit pulls in.

[francesca64]

...and now we're up to winit 0.15.0. Once again, no other changes needed.

[Abendstolz]

Are there really no more changes needed to update to winit 0.15.0? I tried locally and got

error[E0599]: no method named build_vk_surfacefound for typewinit::WindowBuilder in the current scope

Now I am wondering why (Only change from winit ^0.11.0 right to ^0.15.0)

You will also need to change the version in the cargo.toml for vulkano-win.

Thanks. This PR is no longer that relevant but it can't hurt to merge it.
