Using Thor for CLI/scaffold generator. Fancy!

Replaced scaffold generator with Thor::Group/Thor::Actions
bin/napa now uses Napa::CLI (Thor)
Moved lib/generators into lib/napa/generators since they are
    namespaced under Napa
Added app_name to hello_api.rb and config.ru templates, no need to
    manually replace 'HelloWorldService' anymore
Renaming .gitignore.tpl
Fixed a load issue
Made arguments consistent
Merge pull request #21 from benkimpel/thor_cli
