The Lua function 'VPOP3.GetUserSetting' retrieves a user's setting from VPOP3

It takes two parameters:

1. The username
2. The name of the setting. This can either by the 'Name' field of the 'Settings.Settings' database table or the internal setting name

The function returns one value:

1. value - contains value of the setting as a string. Or Nil if the user did not exist
