story-to-pack: add the corpora and the catalogue v2/v3

Fourteen corpora split and classified: aesop, bierce, chekhov, holmes,
keefe, lawson, lorimer, maupassant, nobody, plaintales, poe, torchy,
wallingford and winesburg, each with its splitter and the hand-written
groups and pages; catalogue v2 and v3; and the shared splitters
gutenberg_chunks.py, se_split.py and se_build.py.

+"""Split the Project Gutenberg text of Kipling, *Plain Tales from the Hills* (eBook #1858), into stories.
+Titles are taken from the body, where each story opens with an upper-case heading line ending in a
+full stop, because the contents list has typos ("LESPETH" for the body's "LISPETH"). Every body heading
+is checked against the contents by closest match, and the counts must agree. Each story's opening
+verse epigraph is kept: it is short, and removing it would need a per-story rule."""
