Build a new TokenCacheService so I can stop using TokenService for something it wasn't designed for.

Shouldn't this dependency edge be the other way around? The extensions system
depends on this.

[Andrew T Wilson (Slow), 2013/03/01 17:50:54]

Agreed, this shouldn't depend on ExtensionSystemFactory. In fact, I don't think
ExtensionSystemFactory should depend on this either, unless you need to access
this service from ExtensionSystemFactory::Initialize().

Dependency removed (It was cut and pasted from an example, I should have
understood that it was not required here.)

I don't think you want this. I think you want null in incognito, because
incognito windows are supposed to act as if they are not signed in.

Done.

Why do we need to create this with the profile? Typically, you just have the
service get created when it's needed (lazy-init).

[Pete Williamson, 2013/03/04 18:32:53]

Done.

Why are we doing this? There's no reason not to have this for a TestingProfile.

[Pete Williamson, 2013/03/04 18:32:53]

Done.
