[BUILD] - Fixing classpath within IntelliJ
PRD-5034 - A row-layout band was always marked as keep-together, regardless of what the element style said.
Also: PageBreakPositionList returned wrong results on isCrossPageBreak(..).
Also: Previous version's widow calculation was wrong, as witnessed by the Prd-2087-Widow-2 sample report.
The last group should have kept the last two bands of each group together.
