New: Added Admin page (fixes #30)

Fixes #30

Following are the changes made:

* Supports save and reload of config.
* Picks up the config with a higher priority as mentioned in the README.
* Runs with ```grunt admin```
* Uses react and coffeescript

Any suggestions on how to go about on the below points?

* Support of https ( Need certificates. Related to #58? )
* Restart of other servers on save. (Should ```example.coffee``` be made a module?)
* Graph ( depends on #10 )
Don't think that was the problem. ```through``` module was used in the node env as a part of coffeeify task to create streams out of coffee/cjsx files, and is not required in the browser. The issue was due to some bug in coffeeify.

I would say the current way is the right way to go about browserifying cjsx/coffee files. since, browserify is much more active community-wise and works well when given an appropriate transform module.
