Recompiled version.

You can now adjust playground parameters if you get really bored at a meeting, and simulate every planet's gravitation in our solar system. The main purpose of the app being improving your meeting, I have also added definitions for each role to help you communicate these roles.

I corrected a typo and added a screen in case you really get bored and can't improve someone's else meeting :-). You can now also select the Speech Recognition language.
