Further reduced CPU usage and startup time.

The mute command blacklist can now contain commands with spaces, for example:
If a player types "/f desc ..." while muted, it will be blocked.

Durations for /ban, /mute, etc can now be provided as decimals. For example:
Fixed a bug which could freeze up the server and cause excessive CPU usage.

1.9.10:
Fixed severe BungeeCord task scheduling bug which only occurred when "ban_sync_ticks" was configured.

1.9.11:
Fixed numbers being broadcasted as "1.0" instead of "1".

1.9.12:
Fixed /ipreport not working under BungeeCord.

1.9.13:
Chat events for muted players are now cancelled at highest priority. This should prevent most plugins from interfering with mutes.
