Add an optional flag to "up" for database creation

[lweberk]

Hi,

any thoughts on this? I have an automated build/deploy case in which creating the database manually beforehand is painful. Given the already provided credentials, it would be lovely if dbmigrate up would take care of the initial database creation for me.

If the idea catches up, I'd like to give it a shot.

Best regards, lwk

That would be a good idea I think!
