Watchdog DBlog Exclude

This module adds settings allowing you to exclude specific types, severity levels and ip addresses from being logged to the database.
It does this by overriding the HOOK_watchdog function in the dblog module and implementing its own.
settings are with the other logging settings at: admin/config/development/logging

After implementing this module, I came across one that does virtually the same (though it doesn't seem to filter IP).
