pkg helper is broken

[fesor]

Currently pkg helper is broken since plup uses wrong path to load package.json:

https://github.com/amwmedia/node-plop/blob/master/src/modules/node-plop.js#L112

Basicly node-plop uses path before setPlopfilePath is called, so instead of /foo/bar/package.json it uses /foo/bar/plopfile.js/package.json.

Solution:

+ try { pkgJson = require(path.join(path.dirname(getDestBasePath()), 'package.json')); }

But this is kinda "hack", the problem itself is that plopfilePath contains both file path and directory path depending on time.
