Added option to load a VOCAB file

- Added option to load a VOCAB file.  Creates two global arrays
vocabArray, and vocabSectionTitleArray.  Have not implemented anything
to use these, yet.
- Now allows handling of more than two newlines for asub files and
vocab files (index.Js: see downloadasubfile and parsevocabfile function
updates).  This would cause synchronization issues before.
- minor formatting fixes (removed unnecessary indention) and clean ups
in index.js (parseASUBfile, etc.)
