README-hacking.md corrections and new backup serverHEADmaneage

Summary: this commit will not affect any part of your analysis.

Until now, the following problems existed (their solution that is
implemented with this commit is explained within each):

  - The newly re-organized 'README-hacking.md' file contained the
    "./harvester" term instead of './project'. This happened because this
    restructing was first done in the Arrakihs data reduction pipeline
    (known as the Harvester) and brought upstream (here) after that
    experiment. In the Harvester, the './project' script is renamed to
    './harvester' for more clarity for its users. But I had forgot to
    correct this when doing the merge with Maneage in the previous
    commit. With this commit, the names have been corrected.

  - The 'xlsxio' program depends on 'libbsd', but we had not explicitly set
    this relation through the Make prerequisites. This happened because in
    the past 'libbsd' was built within the "basic" set of software (as a
    dependency of Metastore), so it was present when 'xlsxio' was
    built. But Metastore and libbsd later came into the high-level programs
    and we had forgot to explicitly define this dependency. This bug was
    found by Diana Korotun.

  - The indentations of the './project shell' startup file were too little,
    making it hard to visually distinguish between the text and
    locations.

With this commit, besides the changes mentioned above, the following parts
have also been added:

  - A new backup server (under 'https://archive.org') has been added for
    software tarball download.

  - A new Make tip has been added to 'README-hacking.md' with a minimal
    working example to show how to use pattern rules when there is more
    than one component in the pattern (becomes necessary in large
    projects).
