- New config.json options:
  - customToolbarComponent: Only recognises ‘precisionFDA’ for now
  - pfdaBaseUrl: base URL for the pfda site
- Added config.pfda.json as the base config for a precisionFDA deployment
- Added PfdaToolbarComponent which is used instead of the <mat-toolbar> element in BaseComponent if the config setting customToolbarComponent is ‘precisionFDA’
- Added pFDA icons and images

 - Also added contactEmail

…g expiration, allowing users to extend a session or upon expiration a button redirecting the user to the login page.

 - To enable this feature, add the following to config.json:
     "sessionExpirationWarning": {
       "extendSessionApiUrl": "/api/update_active",
       "maxSessionDurationMinutes": 30
     },
 - The endpoint at extendSessionApiUrl should respond to a GET request and return 200 if session is updated successfully
 - Note that the /login path may be outside of the Angular app (e.g. in the case of precisionFDA)

    "enabled": true,
    "dialogTitle": "Accessing External Site",
    "dialogMessage" : "You will be making an API call outside of the precisionFDA boundary. Do you want to continue?"
  },

 - Better messaging for the PFDA case
 - Disallow closing by clicking outside the dialog
 - Added “Go to Browse” button as an option to stay within the GSRS app

…s is a temporary measure and should be reverted once we upgrade to 3.0, short explanation is that the two 2.7.1 branches used for frontend and backend we used don’t actually match with respect to the name property for substances.

- Also increased spacing between dialog message and action buttons
