Misc refactoring

@EisenbergEffect - creating a PR for these since it's mostly changes to code that you had added originally. I think these are all good things to do, but wanted your opinion before merging into master.

A few misc refactorings and clean up tasks:

- Removed an unused type (CookieTempDataProvider)
- Removed a try/catch from app global startup since no one could remember why it was there (Note: I pushed this branch to a "demo" appharbor site to test out the app start up and see if it bombed out; no issues)
- Removed some hard-coded references to "Tally Code Camp"
- Added some clarifying comments
