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.

 Here is a bit of background information about how we've been running the course
 internally at Google.
 
-We typically run classes from 10:00 am to 4:00 pm, with a 1 hour lunch
-break in the middle. This leaves 2.5 hours for the morning class and
-2.5 hours for the afternoon class. Note that this is just a
-recommendation: you can also spend 3 hour on the morning session to
-give people more time for exercises. The downside of longer session is
-that people can become very tired after 6 full hours of class in the
-afternoon.
