Please read the update notes to fully understand the new feature.

Fix: Missing ar stop from tab complete.
Addition: New command type (bungeedelay:<delay in seconds>), which schedules commands to be executed on the proxy itself. Those commands can only be used in restartCommands and sent on the proxy to be queued for execution when the server restarts. You can now basically run bungee commands without the need of an online player on x server (which is just the stupid way messaging channels work). There's an example in the default configuration. You need to update UltimateAutoRestartBungeePassthrough too!
Addition (API): You can now get the restart delay in seconds from UltimateAutoRestartDelayedEvent with e.getTimeDelayedInSeconds.
