Floating Island World Generation

Major Changes:

• Updated to MC 1.7.2
  
• Added metrics for mcstats.org
  
• Naturally spawning villages using schematics that you provide

Minor Changes:

• Toggle-able option to control placing grass on taiga islands (default: off)
  
• Toggle-able nether portal generation (default: on)
  
• Toggle-able end portal generation (default: on)
  
• Toggle-able zombie pigman spawners (default: on)
  
• Toggle-able obsidian pillars (default: on)

Using a parent generator is subject to bugs out of my control, such as the parent generator affecting the placed islands or crashes because of incompatibility.
