Artisan command "cache:clear"

This implements #31.

Taylor: Do we need a unit test for this? It's pretty trivial.

[taylorotwell]

Looks pretty good. I would just lump the service provider in with CacheServiceProvider with a registerCommands method. Also, I think after the flush we should unlink the $config['app.manifest'] file so the services.json file is re-built as well on next request.

[franzliedke]

I'll do that - I had put it there because that's how you had done it for the session:tablecommand.

And haha, I had wondered whether I should ask again about the manifest file, but when I tested this on a local app, it picked up my service provider changes without complaining...

[franzliedke]

Ah, I see. It only worked because I had created a new service provider. Changing an existing one will not work. Fix is coming.

[franzliedke]

Done, Taylor. Want unit tests, too? (That the manifest gets removed, too, basically.)

[franzliedke]

Ok, my bad. Actually tested now.
