Update nightorder for upstream data change

The script tool's nightsheet.json used to contain character names but
now has identifiers. botc-tools now normalizes and lower-cases before
referencing the nightsheet; this is to patch things up for the current
code which calls the nightsheet with names, but it could also all just
use normalized identifiers.

Fixes #20.
