WebServer functionality restored. (Https instead of http)

TODO:
- Bump Http requests to Https
- Http server if certificate load fails
- No path automatic redirection based on permission level
  - Move to manual authentication instead of Authenticator
    - 403 Page
    - 401 Unauthorized Page
- Tutorial for Keystore creation
