Various code clean ups.

Change Summary & Additional Notes

No functional changes.

Clean ups:

• Rewrap some comments that were poorly wrapped due to past code reformatting.
• Use GridBagConstraintsBuilder in BattleCalculatorPanel to make the code much more concise
• Switch some countMatches() calls to noneMatch() and anyMatch().
• Remove some unnecessary logic prior to calling getMaxUnitsToBePlacedFrom(), since getMaxUnitsToBePlacedFrom() does that logic already.
