configuration setup

[BryonLewis]

resolves #118
Admin/Global Configuration Options for the BatAI application

Currently this will determine if we display/show pulse/sequence annotations in the system. In the future this may contain some more settings for the system.

• Front-End code for disabling Annotation formats
  • On launch for the browser view read the configuration endpoint to determine the current setup of the system. Then disable viewing modes that aren't needed.
  • Add an Admin page where it checks /configuration/is_admin to determine if the user is a super user and provides them with the option to toggle the different fields on/off.
  • The Spectrogram view should only display annotations and tabs for those annotations if the configuration endpoint returns back the correct data.
