Follow stift 9caa240: build, install.lisp and Windows
A new page, Building Programs, describes stift build, linked from Home
and the sidebar, with the command and its API. Getting Started installs
with sbcl --script install.lisp; the pages say where the cache is on
Windows, CCL's program name there, and what the library cannot do in
CCL on Windows.
Getting Started, The Stiftfile, Commands, Starting Lisps, Running Tests,
The Cache and Errors, the API Reference made from the docstrings, and a
sidebar.
