Google is moving toward a default, language-agnostic way of obtaining
authentication credentials on App Engine and Compute Engine.
This change implements this mechanism.
Fixes#90.

Token caching is now done whenever you make a Client, and
ReuseTokenSource is exported from the oauth2 package and used by the
Google TokenSources (Compute and App Engine).
Token.Expired is now Token.Valid, and works on nil receivers.
Some other wording cleanups in the process.
All tests pass. App Engine should pass, but is untested.

- Removed Flow, flow is a nothing but options.
- Renamed Cacher to Storer.
- Removed the setter from the Transport. Store should do the initial set.
Getter is not removed, because extra fields are available through
Transport.Token.Extra(). It's not pleasant to implement a custom Storer
implementation to read such values.
oauth2: Remove VMs from the AppEngine example title
- Reduce the duplicate code by merging the flows and
determining the flow type by looking at the provided options.
- Options as a function type allows us to validate an individual
an option in its scope and makes it easier to compose the
built-in options with the third-party ones.
This change is for both App Engine and Managed VMs so that these apps can scale without running into the app_identity_service quota limit due to calling appengine.AccessToken too frequently. An added benefit of caching is that calls to Google APIs will be significantly sped up due to removing the round-trip calls to the api_identity_service.
