Graph.Community v1.18

Paul Schaeflein -

The Microsoft Graph SDK for DotNet is upgraded to v1.18. Accordingly, the Graph.Community extension is upgraded as well.

In addition, the library has a request builder for user mailbox settings:

GraphServiceClient.Me.MailboxSettings().Request().GetAsync()

(This extension for MailboxSettings is in response to an issue in the SDK repo, and will likely be removed once the service/SDK issue is resolved.)
