Subject: [PATCH] Added time as primary key for SQLite as it makes it take less
 than a second to order by time when you have over 1,000,000 entires in your
 log. MySQL seems fine as it has a cache. If someone who uses MySQL finds this
 wrong, please ether add in the primary key system yourself and submit a patch
 or let me know in a bug report.
