Use last version of `vinyl-fs` (~0.1.2) to avoid node-gyp/gaze issues

Currently configured `vinyl-fs` (**0.0.2**) needs native compilation using `node-gyp` for `gaze` dependency crashing on non-developer/compiler configured machines.

**NOTE:** Same issue as jsBoot/gulp-jsdoc#9 and jsBoot/gulp-docco#4
