[Feature request] Create Spark user account by script

Hi,

When installing computers for new employees (fully automated) we are creating the user's Spark client account with some powershell magic, but it would be really helpful to have some console options to precreate an account and define server settings.

e.g.: spark.exe -create -username <username> -password <password> -server <server> -oldssl -proxy <proxy>
