Changed mind re: "is_valid" requirements for the Minor Decision - is probably important to have them, if nothing else so that people know what the requirements are. Also will allow one to use the "notify me when decision becomes available" toggle for it.

-Removed the "is_valid" requirements for the Minor Decision since one of the choices will be valid most of the time.
-Tweaked the Minor Decision language again, a bit, because I was still not happy with it.

-Changed the text for the Minor Decision to make it more broad re: why one would want to withhold or deny levies.
-Tweaked the opinion debuffs so that if a liege already has a debuff against you for refusing levies you won't get an additional debuff if you choose to withhold levies (to prevent some punishment for softening your position, but also, just to generally not pile-on the debuffs)
-Reworked some logic so that belligerent players are now caught by the monthly/yearly periodic checks of validity.

Just a minor tweak for players when their liege goes to war to do a validity check on their current belligerence, and if they don't meet the requirements (if they're terrified, imprisoned, liege has a strong hook), reset them back to their standard obligations.

Players can now (if requirements are met) choose to withhold/deny/restore their levy obligations to their liege via a Minor Decision.

Tweaked the punishment rule to have title revocation be the default so as to be backwards compatible with anyone still playing the mod pre-rule

Added a rule to choose the punishment for refusing levies - title revocation, imprisonment, or both.

Added context to the "Liege Calls Bannermen" event window so that the vassal is told if the war is an offensive or defensive war, and who the opponent is.

-Tweaked the new vassal/liege logic so that low opinion of new liege isn't necessary for the checks to occur
-Adjusted timing of events so withholding/refusal notifications shouldn't go out after war has ended
-Added some groundwork for players refusing martial serive & levies

Fixed a scope error in the contract validation
