[darkroom] Darkroom out of service until tomorrow afternoon

[sen]

The shutoff valve for the new Intellifaucet feed on the darkroom plumbing
was damaged in a steam explosion this evening, so the darkroom plumbing is
all shut off until I can replace it. Daria and I will get that done
tomorrow afternoon so the darkroom can at least be functional like it was
until we finish the Intellifaucet installation. Until then, the darkroom
is not usable.
