B2016-262 & B2016-263: for search results & report, print ‘Equation’ for Document text rather than rtf

Additional functionality for Equation Editor, bring up equation editor tool (from registry setting) on Equation button click
B2016-265, print proper size of change bar
B2016-261: don’t print extra blank lines for a table/equation/figure after caution/note off many lined step in single column mode
