No support for tables names different of model names

[mtancoigne]

Currently, superBake creates models expecting the corresponding table exists.

An option should be created in the config file to handle this, and the sbc::populate() method should take care of it.

defaults:
  model:
    ## Model name
    name: <modelName>
    ## Table name in DB
    tableName: <tableName>
    <other options>
