Add invitePriorityQuest trigger

[douglasrizzo]

This PR adds a new auto quest invite function that prioritizes sending invites to quests which the party has completed the least.

It addresses the topics mentioned in discussion #47.

1. Quest information is gathered.
2. "Party quest completion percentage" (taken from quest-tracker) is computed.
3. Quests are sorted in ascending order of completion %.
4. The first quest which the player has a scroll for is used.

The README may need an update to detail how to use this. If the change is welcome, I can do it as well.

I've printed a log of the decisions the script makes.

The single reward quests my party has completed recently has a 100% completion rate, while there are also quests I have never done that have a small completion rate. So I am fairly sure the script is working.
