Option to automatically return to body and improve tutorial messages

[spig95]

Changes

• Add an option to automatically return to your body when the noclip camera returns to it, this option can be easily switched on/off using the scriptable object noclipOptions
• Useful feature (in my opinion): in any case, the player does not move after activating noclip, pressing P makes it return to the reality body even if it does not goes away from the body and return
• Disable the "press P" text when the player exits from the noclip enabler

Remarks

• I also improve slightly the tutorial controller. Now, for instance, we actually use the serializefield to decide the hint duration. (@bottolo: the change I mentioned to the GUI scene is that I changed the value of hintDuration from 0s to 4s in the serialize field of the tutorialController component)

Okay, I see what you did there and yes, it's much more clearer this way. Also, there was redundancy between "Press P" and "DisplayHint", so it had to be removed or changed.

On top of that, clearing up text is a nice addition.

Everything works as expected.

I've found that automatically switching mode is definitely smoother and more satisfying. Perhaps we could add this option to the gameplay ones to let the player customize his/her experience, although it seems that feedbacks lead us to the automatic switch solution. We'll see.

After trying it, I must admit it is indeed better to automatically return to the body :)
