Create SQLite index for Messages table

Browse Source 
This significantly speeds up certain SQL actions on
the Messages table that were done for anti-flood detection.

The bot should now be significantly more quicker to catch
floods promptly without delay.

(Also, comment out some logging messages. Perhaps revisit this
and wrap them with a debug registry variable instead.)
