Level Generation Settings

I've added a few settings to be able to customize how the level is generated.  This only applies to the platforming section.   

The settings include:

•  whether to generate gaps
• the maximum size of the gaps 
• whether to generate spikes
• the percent chance that spikes will generate
• whether to have the 'darkness' effect while playing

I plan to add more settings but this took me a while already.  Some other settings I plan to add are

• Whether to generate wooden platforms
• whether to generate stone platforms
• the max size of wooden platforms
• the max size of the stone platforms
• the percent chance to generate stone platforms
• the percent chance to generate wooden platforms
• the amount of enemies that will spawn
• player gravity
• potion drop percentage
