Update "Magnificat"

[Jim-Duke]

Review the next version of "Magnificat" after all the recent changes. This version should have improved upon all of the following:

• Layout
  • [x] Suitable for binding "inside" margin wider than the "outside" margin.
  • [x] Combined parts - two voices on the same staff are printed as chords as opposed to separate stems, except when the parts differ or are identical, or near identical notes. (More conformant to standard hymnal styles)
  • [x] Better sized fonts on sheet music
  • [x] Much larger font and notes on slides
• [x] MP3's run the full length of the hymn - all verses.
• [x] MP3's use a different instrument for the dominant voice (Piano).
• [x] Proper number and pagination
• [x] Inclusion in Table of Contents and Index
• PresentationCreator v2.0 packaging
  • [x] Updated hixml data
  • [x] Verse text in metadata
  • [x] Build processes to copy and zip all appropriate parts
  • [x] Tested with PresentationCreator v2.0

Relatively small nit: the systems on the first slide of the "All Sing" portion extends all the way to the right edge of the page. Spacing is tight; but if possible this should be pulled in just a tad.
