Settings screen for OAuth tokens

The new screen is visible if authentication type OAUTH is enabled
for Git over HTTP communication (auth.gitBasicAuth = true).
It shows the value of the access token that is assigned to the
current web session, the expiration date of the token, and the
corresponding entries for the .netrc and .gitcookies files.
