--check-init & --set-mods + fixes

[DameryDad]

• Fixed creature initiative where creature has both innate and weapon attacks
• Provide --check-init and --set-mods commands to add and remove modifiers to initiative rolls and record them in a table, with a dialog to show to players.
• Fixed detection of creature innate attacks where none exist, and count them where correct count field not recorded.
• Made default attack initiative setting more reliable. Adjusted "Set Round No." default to blank which defaults to +1.
