At long last

This quickfix corrects the non working HoW feature (mostly geared toward PBEM admittedly).
Decisions
* Effects of Circumvallation Decision (now entrenches the stack level 4)
* Effect of "Offer Honors of War": the decision now lasts 3 turns, allowing the besieged player to accept it (don't miss the message, if not responded on turn offered, it will be withdrawn).
* Reject or Accept Honors of War: fixed too
Update Kit
* Added a missing set of graphics for ledger shortcuts
* Added missing filter buttons update

As all quickfixes, you need to apply the latest full patch before (in a sticky in same forum).
