Revision 765272

Some cleanup:
  * extraction of the footnote-related loops in getNextKnuthElements() into private methods 
    to facilitate step-over when debugging (no additional breakpoints needed to skip those loops)
  * merging of the private doPhase3() methods, so theoretically, it becomes possible to do 
    column-balancing, even with a last page condition, and to eliminate a significant amount 
    of duplicate lines of code
  * other minor changes, like renaming stray Hungarians, renaming some variables to make the 
    code slightly more self-explanatory, removal of unused import, and whatnot...
