Changes:

• added the 'Flat' noise type. It is basically a flat world, but with all structures, biomes and caves
• falling blocks fall immediately after being placed in an unfortunate position
• added options to change the gamemode and to regenerate the current chunk to the Creative Controls screen
• added items that spawn structures
• added option to change noise scaling, handled by the brand new slider widget
• added restrictions for survival mining. Yet no tools are present
