Added and fixed unit tests 

Aside from testing our new module (network.js), we also had to add logic that would test Filer appropriately in both the node and browser environments.

* `grunt check` will run [JSHint](http://www.jshint.com/) on your code (do this before submitting a pull request) to catch errors
* `grunt develop` will create a single file version of the library for testing in `dist/idbfs.js`
* `grunt release` like `develop` but will also create a minified version of the library in `dist/idbfs.min.js`
* `grunt test` will run [JSHint](http://www.jshint.com/) on your code and the test suite in [PhantomJS](http://phantomjs.org/)
* `grunt test` or `grunt test-node` will run [JSHint](http://www.jshint.com/) on your code and the test suite in the context of `nodejs`
* `grunt test-browser` will run [JSHint](http://www.jshint.com/) and start a localhost server on port `1234`. Navigating to `localhost:1234/tests/index.html` will run the test suite in the context of the browser. **NOTE:** When finished, you will have to manually shut off the server by pressing `cmd/ctrl`+`c` in the same terminal session you ran `grunt test-browser`.
Once you've done some hacking and you'd like to have your work merged, you'll need to

## Tests
Tests are writting using [Mocha](http://visionmedia.github.io/mocha/) and [Chai](http://chaijs.com/api/bdd/).
You can run the tests in your browser by opening the `tests` directory. You can also run them
[here](http://js-platform.github.io/filer/tests/).
You can run the tests in your browser by running `grunt test-browser` and opening the `tests` directory @ `http://localhost:1234/tests`.
There are a number of configurable options for the test suite, which are set via query string params.
First, you can choose which filer source to use (i.e., src/, dist/filer.js or dist/filer.min.js).
The default is to use what is in /src, and you can switch to built versions like so:
First, you can choose which filer source to use (i.e., src/, dist/filer-test.js, dist/filer.js or dist/filer.min.js).
The default is to use what is in /dist/filer-test.js, and you can switch to other versions like so:
* tests/index.html?filer-dist/filer.js
* tests/index.html?filer-dist/filer.min.js
* tests/index.html?filer-src/filer.js (from src)
Second, you can specify which provider to use for all non-provider specific tests (i.e., most of the tests).
The default provider is `Memory`, and you can switch it like so:
