[BUG] Link from Cursive::new to CursiveExt doesn't work offline.

[masklinn]

I'm not sure how to resolve this. I think the ease of getting and using documentation offline is one of the strength of Rust, but because cursive_core::Cursive::new is linking downstream it can't use "local" links, even though it's linking to a sibling crate, and will usually be generated as part of the cursive documentation & re-export.

Somewhat linked to rust-lang/rust#24305 "Pain points of reexports"
Definitely linked to rust-lang/rust#74481 "Figure out a way to link to downstream crates"

Right, that's one of the issues with the current crate organization. As mentioned in the linked threads, one workaround would be to re-document the re-export in the cursive crate itself, but that would:

• Prevent using use cursive_core::*;, and instead force me to import each module one by one.
• Duplicate the documentation between the two crates, with the risk of one getting outdated or even diverging. Maybe this could be solved by instead doc-linking to a shared markdown file?
• We can only re-document items like types, modules and free functions this way, not methods on a type.

So for now, I think hard-coding the link to docs.rs is the lesser evil.
