Support for Acronyms / Glossary

— Added support for a list of acronyms (glossary).
· There are separate files for each type (acronyms.tex) and
(glossary.tex) and examples of usage in Chapter 1.  Although, both
acronyms and glossary entries will be printed in the same (sorted) list.
— Now the template will still work if the non-mandatory files
(dedicatory, quote, acknowledgments) are absent.
