myPrayerJournal v2 (#27)

App changes:
* Move to Vue Material for UI components
* Convert request cards to true material design cards, separating the "pray" button from the others and improved highlighting of the current request
* Centralize Auth0 integration in one place; modify the Vuex store to rely on it entirely, and add a Vue mixin to make it accessible by any component

API changes:
* Change backing data store to RavenDB
* Evolve domain models (using F# discriminated unions, and JSON converters for storage) to make invalid states unrepresentable
* Incorporate the FunctionalCuid library
* Create a functional pipeline for app configuration instead of chaining `IWebHostBuilder` calls

Bug fixes:
* Set showAfter to 0 for immediately recurring requests (#26)
