flatten whistle projection to have fewer functions in files to improve readability

[torstees]

The current approach to creating few, large whistle "modules" is borrowed from google's examples. Because a lot of functions have ended up being used by more than one "module", placing these in their own file will make the projectors easier to read overall. Also, modules that contain related but very different resources make for slower development times as the files have become large in some cases. Having more clearly named whistle files with a singular purpose seems likely to be a better approach than globbing all questionnaire related resources together in the same massive module.
