Version 1.0.1 in CMakeLists.txt and amorph_results.py, and its section
in CHANGELOG.md: the export_pgf defaults of #17, the GitVerse mirror and
the README of #16. The sampler is that of 1.0.0.

GitVerse refuses release files over 100 MB, and the GUI package for Linux
is 119 MB: that is why v1.0.0 could not be uploaded there by hand, and
the mirror would have stopped at that file. The mirror now moves the
files over 100 MB out of release/, uploads the rest, and adds links to
the files left on GitHub to the notes of the GitVerse Release. GitVerse
releases start with v1.0.1, so the README drops the steps to publish
v1.0.0 there by hand, and its Downloads section names the GitVerse
releases.
