Add ACKS II Initiative: The Tracker should automate the ACKS II style Initiative sequencing

[ArcanistWill]

Use Case: Initiative Sequence

Setup / Before First Round of Initiative Just before Initiative is rolled (for the first round), this happens:

• The system determines which characters are Surprised - this only happens once in the fight.
• The system determines which side is Outnumbered - this happens at start, and can happen on every following round.

Main Initiative Sequence The Initiative sequence below repeats until the Judge ends it:

• Initiative is rolled for all combatants using 1d6 + initiative modifier = Initiative Count
• Combatants are sorted by count in reverse numeric order, (then by Outnumbered Side, then by alphabetical order)
• The Initiative Tracker then displays the results as a countdown from 10.
• Initiative Countdown happens: At each countdown (10, 9, etc)
  • All characters eligible to act from each side are listed in alphabetical order by side, starting first from the Outnumbered Side.
• The system should sequence down from top to bottom to allow the Judge to step through each character's turn to act
• Initiative Options:
  • The Judge clicks on a character’s Initiative to mark the character as “Done,” “Delaying,” “Readied,” or “Unconscious.”
• At the end of the initiative count
  • the system might recalculate which side is Outnumbered
• At any point during the initiative count
  • the the Judge can choose to end the sequence and step out of Initiative

I confirm that the Initiative feature is completed and the Initiative branch can be merged to master.
