Compatibility update for the new BKCommonLib 1.14.4-v1 (Minecraft 1.14).

Changes

• Make compatible with new changes in BKCommonLib 1.14.4-v1
• Fix Variable get(name) returning a default value, instead of the per-player value
• Fix recursive chunk loading during linked-sign discovery (improves performance)
• Fix signs no longer refreshing their text (when changed by other plugins)
