[suggest] Procedurally generated paths

Issue Description:

Add natural paths generation by RTG

Steps to produce paths
  1. Use Perlin Noise Terrain Elevation and, or, Biome Distribution data for path frequency and width to determine if x,z has a path run at y=surface
  2. Perform path rendering from blocks substitution rules.
Path blocks substitution Rules
Condition Surface Replacement Rule 
block(y+1)=="air" && (
  block(y)=="grass" ||
  block(y)=="potzol" ||
  block(y)=="mycellium" )
 
block(y)="grass path";
block(y+1)="air";
 
block(y+1)=="air" &&
block(y-2)!="water" &&
block(y-2)!="flowing water" && (
  block(y)=="water" || block(y)=="flowing water" )
 Draw a ford across shallow water 
for( px=x-1; px==x+1; px+=1 ) {
  for( pz=z-1; pz==z+1; pz+=1 ) {
    if( block(px,y,pz)=="water") {
      block(px,y,pz)="flowing water";
    }
  }
}
block(y-1)="cobblestone";
if( Random.nextFloat()<.25f ) {
  block(y)="mossy cobblestone";
  block(y+1)="air";
}
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="stone" )
 
block(y)="cobblestone";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="cobblestone" )
 
block(y)="gravel";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="gravel" )
 
block(y)="dirt";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="dirt" )
 
block(y)="dry dirt";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="sand" )
 
block(y)="sandstone";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="sandstone" )
 
block(y)="hardened clay";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="snow block" )
 
block(y)="ice";
      block(y+1)="air";
 
( block(y+1)=="air" || block(y+1)=="snow" ) && (
  block(y)=="snow block" )
 
block(y)="ice";
      block(y+1)="air";

I think this is probably a little outside RTG's scope.
