v3.2.1

• Use of the [ValidateAntiforegeryToken] attribute for each API method individually, because using this attribute for the entire class extends its effect even on GET methods and it is invalid behavior. #123
• Added new OnlyRegisteredUserAuthorizationHandler policy to restrict access to some views for non registered users.
• Added infrastructure to work with platform API by using OAuth2 access token authentification.
• Fixed the bug with the out-of-sync of cached security data between the storefront and the platform #111 #112
• Fixed bug with wrong product availability evaluation due to that fact that the store default fulfillment center wasn't taken into account
• The replaced use of the ValueObject.GetHashCode method in the construction of the cache key to string because of the high probability of duplication of hash values
• Removed cart totals calculation from model properties. There must be only one place for this, cart module API.
  #122
