Fix maxCheckboxes spelling in trackDb docs, which listed it as maxCheckBoxes.
Setting names are case sensitive and the browser reads the lowercase form, so
hubs copying the documented spelling silently got the default. Also adds
level-new tags to the faceted composite settings metaDataUrl, primaryKey,
maxCheckboxes and dataTypes so hubCheck -checkSettings recognizes them instead
of reporting them as unknown. refs #37965

 This setting is required and works in tandem with the file specified in the metaDataUrl
 setting.  The named field will be used as a primary key for the metadata table, and
 those values will be used to identify subtracks.

 Frequently a facet may have a long list of possible values - too many to display at once in
 the track selection interface.  This setting limits the number of facet values displayed on
 the left to the N most common, where N is the value of this setting.  The default value is 20.

 This optional setting identifies a list of datatypes available for each sample in the metadata
 file (one sample per row). Each datatype is identified by a name, which is combined with the
 name of the parent track and a primary key to form track names as described above.  Spaces
 cannot be used in data type names; instead, spaces separate the various data types.  If present,
