Terrain Generator V0.7

• Stamp mode: This mode can be used to stamp hills or valleys onto the terrain.
• Paint a solid colour instead of a texture
• There is an option to change the control scheme if you have an AZERTY keyboard
• The linux version defaults to using the Vulkan graphics API instead of OpenGL
• When loading saves from version 0.1-0.3 it will now select the correct material and factor value
• Saves the ambient occlusion setting
• Fixed errors that happened when using a rotated brush partially off the terrain

Note: I don't have access to an AZERTY keyboard. I think it works correctly, but I'm not 100% certain. If anyone with an AZERTY keyboard notices any errors then let me know
