Add an Expert/Simple mode

[Picaut]

Not all the functionalities should be necessary for all users. By default, a simple mode should be enough for most of users (for example all results seem not necessary). The expert mode could be used only by Pro. Expert/Simple modes should be a parameter in the Settings.

OK. And maybe, once you launched NoiseCapture for the first time you could have a panel to choose your profil (instead of a default parameter) ?

Yes. Finally, not a priority, I move it to the release 2.
