Subject: * Replaced (possibly broken?) math for calculating the unix timestamp
 in MySQLAssetData with Utils.DateTimeToUnixTime() * Disabled
 UpdateAccessTime() function since it was only writing zeros anyways. This
 gave me a significant performance improvement for startup times and avatar
 logins in standalone mode * Load attachments asynchronously so avatars with
 lots of attachments don't have to race the timeout clock to login
