[TH NH] file management with accounts
[NH] Minor bugfixes and wrote feed interceptor tests.
[NH TH] change find-by-token to validate-token
[TH] define hermes auth token magic string
[TH] rename parameters with dash instead of underscore
[TH] normalize keys in entities so we can use dashes everywhere
[JE NH] Moved normalize keys to db namespace and generalized keyword conversion.
[TH] use normalized keys in rendering
[TH] add User model, move api-key to user, make feeds many-to-one on user

This structure should work better with an FTP based solution.
