localRepository and debug should be configurable via package.json

[alan-czajkowski]

package.json supports:

    "java": {
      "repositories": [
...
      ],
      "dependencies": [
...
      ]
    }

but it would be nice if you could also configure localRepository and debug:

    "java": {
      "debug": false,
      "localRepository": "./lib",
      "repositories": [
...
      ],
      "dependencies": [
...
      ]
    }
