* 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
