Small fixes:
 - Model baking : options from config file are now well cleaned at the end of the process
 - Controller baking: options from config file well cleaned too (previously unsetting the wrong vars)
 - Method displayArray() moved from Theme class to SbShell class
 - Model baking: now you can define "actsAs" in config file, instead of including a snippet. Just define an `actsAs` section in the model options.
 - Menu generation for Template documentation now fixed.
 - Config file population : fixed models options population
