Fixed Servor error in user groups

Hello everyone, just need to report something wrong again. (@Mike)

When editing a user group (administration part of XenForo), just put as display styling priority a value like this : 999999999999

["_POST"] => array(9) { ["display_style_priority"] => string(12) "999999999999" }

Server Error
Mysqli statement execute error : Out of range value for column 'display_style_priority' at row 1
