Make Mycroft tell that it's looking up the requested information

[PureTryOut]

The query "what type is pikachu" cause Mycroft to be quiet for a second or 10, at which point I thought it would never answer. Luckily it did after all, but it would be nice if Mycroft told me it is looking it up and it might take a few seconds.

OK. It's been a while since I've tested this, but I do remember that happening. With the way I currently have it set up, I believe it's difficult to tell if it's making a request to the API, or if it has cached data.

I will try and think of ways to fix this in the next release.
