Initial implementation of JSLint gulp plugin

>Interesting suggestion, but this project is too small for this IMHO.
If updating paths becomes an issue in the future, we can switch then.

I worked on a large `PHP` project, where file includes were all done with strings. It became very troublesome very fast. Perhaps in this module it is too small to care, but it is definitely something to keep in mind.

I am not as familiar with node, but what I did with PHP was something like:
`var config = $_SERVER['DOCUMENT_ROOT']."/CONFIG";`

Where I was able to get the root path of the site / folder, and then get the config file like that (from an absolute path, so not having to worry about `../../../`).

So what I ended up doing, was off of the main root, I had a `CONFIG` file that mapped to all my module `CONFIGS`, and then those module configs would map to their respective files.

```
// get configs handles
var rootConfig = require(_FANCY_NODE_ROOT_VAR_" + "/CONFIG");
var configModuleA = require(rootConfig.configModuleA);

//get dependencies
var fileA = require(configModuleA.fileA);
```

This isn't elegant (but it was also about 3 years ago when I designed it), but it got the job done... I could call multiple different configModules, and resolve dependencies from multiple places as long as I had a handle to their config files.

Anyways... Perhaps something along these lines could be investigated.
