Fiber-seq: sentence case for the Common cell line sample class, which was
Title Cased because that is how Mitchell wrote it in the mail that gave us
the classification rule.  The other two values were already right, and
tadsEncode's organ facet is the precedent (Adrenal gland, Bone marrow).  The
swatch table on the description page had been saying "Common cell line" in
its prose all along, so the filter label and the text explaining it now
agree.  fiberSeq.ra is untouched: the class only lives in the metadata TSV
and the colors JSON, both read at runtime, so no trackDb reload is needed.
