./gradlew runClient does not work about chunkgen HOT 5 CLOSED

The assetDir is deprecated!  I actually just did all this generalizing stuff just now.. Use runDir instead! runDir set to eclipse/assets/..
The runDir should be the location where you want MC to be run, usually he parent of the asset dir
