Support for Create database patch files

[sndpl]

If you add a create database statement in patch-001.sql the statement files because there is no database yet. Would be nice to have support for this kind of patches.

Idea's:

• Add a new command that executes a create.sql
• Detect the database doesn't exists error and then create the database automatically or execute a create.sql
• Add a param to the update command to execute patch-001 first without doing other things

Suggestion ask user if db should be created as alternative fot either autocreating it of requiring a parameter. That said, doe this work with CI etc?
