Four Horsemen Assistant (4H Assist)

* In live mode, the map will now properly reset if you release spirit before the encounter officially ends.
* When the bottom bosses are dead, the position indicators will now disappear for all roles except the four top tanks.
* Removed the padding between the mark counts and edge of the map (which was inadvertently added in v0.6.0).
* Fixed some minor performance issues with the range check, and changed it to check every second instead of every 0.5 seconds.
