Add error check for label mask in OMNI_ASSOC_CATALOG

Add error check in omni_assoc_catalog.pro for an object that does not appear in
the supplied label masks.  The check then skips the object and spits a warning
message to the user that the label masks should be inspected.

Fix 'object not in label mask' bug in OMNI_GRSMATCH

Fix a bug wherein an object not present in the label mask had caused
omni_grsmatch.pro to combine the spectra from EVERY point in the map NOT
associated with a source.  Now simply skips the object.

Add feature to OMNI_GRS_SPECTRA_LOCAL to save only full catalog

Add keyword and check to NOT save the IDL structure to disk if START or REAR
is specified unless FORCE_SAVE is set.  This avoids debugging checks from saving
undesired data.
