Added a notification for when a muted player tries to chat while muted.

Added a configurable throttle duration (default 10 minutes) for ban and mute notifications ("<player> tried to join, but is banned" / "<player> tried to speak, but is muted").
This means that players can't flood admins/moderators with these notifications by doing the same action in a short period of time.

Some minor performance improvements.

Default config.yml changes:

"delete_previous_history: true" set by default as it improves performance, especially for SQLite databases.

Default table prefix is now set to "litebans_".

Default mute blacklist now includes all Essentials private messaging commands.

Fixes:

Commands are now treated as lowercase for mutes.

You no longer need to add a space after every command in the mute blacklist to prevent blocking "/warp" with "/w", for example.

Possibly fixed mutes not working with DeluxeChat and other plugins listening at highest priority.

Improved performance with AuthMe integration.

1.9.17:
Fixed MySQL indexes being created twice for new tables.
