multiple scaffolding folders

Hi,

Based on my experience using Grails since 1.3.x, I've requirements to have multiple scaffolding folders. e.g:
src/templates/scaffolding
src/templates/another-scaffolding-set
....
So, I want to propose an improvement to generate-all script by adding option to select which set of scaffolding to use (default is still src/templates/scaffolding).
How do you think about this?

Start with the generate-all script and the existing src/templates/scaffolding directory described in the issue. Trace how the default scaffolding set is selected and determine what behavior is needed for an alternate folder while preserving the default. Done means generate-all can select among multiple scaffolding folders without changing existing default behavior.
