Comprehensive Rust v2 (#1073)

I've taken some work by @fw-immunant and others on the new organization
of the course and condensed it into a form amenable to a text editor and
some computational analysis. You can see the inputs in `course.py` but
the interesting bits are the output: `outline.md` and `slides.md`.

The idea is to break the course into more, smaller segments with
exercises at the ends and breaks in between. So `outline.md` lists the
segments, their duration, and sums those durations up per-day. It shows
we're about an hour too long right now! There are more details of the
segments in `slides.md`, or you can see mostly the same stuff in
`course.py`.

This now contains all of the content from the v1 course, ensuring both
that we've covered everything and that we'll have somewhere to redirect
every page.

Fixes #1082.
Fixes #1465.

 # Pattern Matching
 
-The `match` keyword lets you match a value against one or more _patterns_. The
-comparisons are done from top to bottom and the first match wins.
-
-The patterns can be simple values, similarly to `switch` in C and C++:
-
-```rust,editable
-fn main() {
-    let input = 'x';
-
-    match input {
-        'q'                   => println!("Quitting"),
-        'a' | 's' | 'w' | 'd' => println!("Moving around"),
-        '0'..='9'             => println!("Number input"),
-        _                     => println!("Something else"),
-    }
-}
-```
-
-The `_` pattern is a wildcard pattern which matches any value.

-Key Points:
-* You might point out how some specific characters are being used when in a pattern
-  * `|` as an `or`
-  * `..` can expand as much as it needs to be
-  * `1..=5` represents an inclusive range
-  * `_` is a wild card
-* It can be useful to show how binding works, by for instance replacing a wildcard character with a variable, or removing the quotes around `q`.
-* You can demonstrate matching on a reference.
-* This might be a good time to bring up the concept of irrefutable patterns, as the term can show up in error messages.
