fix up path issue in build.sc

Whereas in the past, the user was expected to provide the firtool binary
on the PATH, Chisel will now manage the firtool binary automatically.
Chisel users the following 3-step process for determining which binary
to use:

1. If environment variable FIRTOOL_PATH is set, it will check for
   firtool in that directory
2. It will check the classpath for firtool provided by
   chipsalliance/llvm-firtool
3. It will download a default version of chipsalliance/llvm-firtool

Both (2) and (3) will store the firtool binary in a sensible location
depending on the user's operating system. See dirs-dev/directories-jvm
for more information. The user can override this location by setting the
FIRTOOL_CACHE environment variable.

Go all in on leaf marking for don't touched values. This preserves current behavior. As options expand, the API can change then.

Add an argument to dontTouch which allows placing don't touch annotations on the leaves of aggregates. Default this option. This results in the same behavior as what the current dontTouch effectively does today. Don't touch of an aggregate is on it's plain meaning different from don't touch on the leaves of an aggregate. Making the annotation a bit more precise allows greater freedom in code generation and allows catching contradictory requests by the programmer.

This is the right place in the Chisel type hierarchy for Property as
it exists today. Property types can be used in Aggregates, and are not
themselves Aggregates in their current form. Making Property extend
Element allows much of Chisel's internal reflection to work as
expected when Property types are used in Aggregates.

Add a `dontTouchLeaves` which places don't touch annotations on the leaves of aggregates.  This does what the current `dontTouch` effectively does, but is explicit.

A dead import dies.

Fix spelling error

This should enable them to be indexed and thus searchable as part of the
website (both by Algolia and by Google).

* Rename docs/introduction.md to docs/index.md so that now the main link
  is just /docs.
* Add redirects for some common links from the old sbt microsites
  website.

Add tests (also demonstrating new ability to walk alignment of bare types).

Use Github logo for link instead of just text.
Improve Makefile dependencies for `make build` to actually depend on the
source files in website/.

With default settings, contextual search breaks search results.
