Added Baseline for fix to #64

Baseline fix to #64. Needs an in-progress message to be defined to look for in the server log, but the logic is it checks the most recent 50 lines in the log for an "In progress" statement from WorldBorder.

WB by default (and this cannot be changed) prints to the server log every 10 seconds.

If It Fails to find an in progress message in the last 50 entries, WorldHandler will restart the job. If the job is actually in progress no harm is done as the command does nothing.
