add possibility for adding tablename

[ghost]

Not sure how hard it would be but when creating new migration scripts for create table it would be cool if one could add the table name so that the migration script would already have the table name in the createTable and dropTable function.

My fork/pull request now enables pre-filling in the table name for all of the migration templates.
