MARC tooltip updates

MARC tooltip updates

* updated bibliographic tooltips; now current as of LC MARC21 Bibliographic
  Update 11, including the RDA tags.  Along the way, enhanced the bib tooltips to:
  * include definitions for embedded holdings tags (84X, 853-855, 863-868, 876-878)
  * expand dropdown for nonfiling indicator values
* added tooltip files for authority records and MFHDs
* taught MARC editor how to choose the correct tooltip file

Caveat: if you localize the authority and MFHD tooltips for a locale other than
en-US, you must edit marcedit.js, either to take your translation into account
or to make it smarter about checking for available translations of the tooltips.
