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": [
...
 ]
 }
