Explicitly write down 0.1 release date in RELEASES.txt, to confirm Rust's birthday.
Index cross-mod type definition and implementation properly in rustdoc

A structure's definition and implementation may be cross-module. If the
implementing module is parsed before defining module, the fully
qualified name of the structure won't be present for the implementation
to use when being indexed. So caches such 'orphan' implementation and
indexes it at the end of crate parsing.

Closes #10284.

libstd: Add some more functionality to Vec<T>
librustc: Automatically change uses of `~[T]` to `Vec<T>` in rustc.
librustc: Fix up fallout from the automatic conversion.
librustdoc: Fix librustdoc for the `Vec<T>` change.
Incorporated review feedback atop pcwalton's original patches.

(Original PR was #12716; feedback was provided by thestinger and me.)
auto merge of #12768 : pnkfelix/rust/fsk-devecing, r=pnkfelix

Change `~[T]` to Vec<T> in librustc.  Rebased and amended version of PR #12716.

Original author (or perhaps I should say meta-author) was @pcwalton, as is reflected in the commits.

I clean up!  :)
