A master-loot raid roll that never finished no longer lingers. If the loot window closed part way
through, or the result never arrived, XLoot kept waiting indefinitely, and the next loot window you
opened could have an item handed out from the old roll. XLoot now stops waiting when the loot window
closes, gives up on its own after fifteen seconds, and tells you when a roll was discarded.
Improvements
Master loot now sends its announcements through the same chat path as the rest of XLoot, the one
hardened against the "secret value" errors that 12.0 introduced in instanced encounters.
