Combined Creative-Survival mode

What do you want done?

Add combined Creative-Survival mode.

Why do you want it done?

It helps start a game in Survival model more easily, especially for new players. It also broadens player experience.

How do you want it done?

Provide functionality from Creative mode that is currently not available in Survival mode:

• Get basic starting inventory like a pick axe, sword, chest plate and boots without having to break things to get materials and make them
• Ability to fly – for both player and mobs, maybe
• Ability to press and hold “Shift” and click on a block to get a whole stack of the material

The rest can be as it is in Survival mode right now.
