refactor: Synchronously load user templates and data on startup.

Since I had to use Forever to reload helpers anyway, I determined it was redundant loading templates on every request just so they're always up-to-date. If they change, Forever will restart the server and they're reloaded.
Make start scripts start forever-wysia.
fix: Partial template detection by file extension.
refactor: Get initial shared state from user_models.

Was reloading it unnecessarily.
