refactor: DRYify render function internal step calls.
refactor: Drop unnecessary else clause in load_shell.
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.
