Decompiling TerrariaServer

For functional API:

1. Decompile TerrariaServer with Reflector, ILSpy, dotPeek, etc
2. Fix errors resulting from decompilation
3. Add API hooks
4. Update hooks/functions/documentation for any code changes Redigit might have done

OR (if small update)

1. Decompile
2. Diff
3. Patch

For Mono support:

1. Remove XNA references and reference our internal Color/Vector2 classes instead
2. Remove P/Invoke's
3. Add Mono-specific networking changes (Async writes need to be replaced with blocking writes)
4. Fix any paths that might be broken on Unix systems

Extra stuff:

• Pack the Tile class
• Refactor the code
• Fix bugs left in by Redigit
• Remove client code to shrink file size
