Subject: Add support for alternative build file/directory naming scheme

Now the build/*.build, buildfile, and .buildignore filesystem entries in
a project can alternatively (but consistently) be called build2/*.build2,
build2file, and .build2ignore. See a note at the beginning of the Project
Structure section in the manual for details (motivation, restrictions,
etc).
