Backend-less Firebug-like mode

[ivankravchenko]

You know, it would be great for some use cases to make Styler to work like Firebug – without project configuration and without backend.

Positives:

• simple usage – just install browser plugin – no nodes installation, no backend running, no project configuration is required
• great for cases where file saving isn't required or not possible

Negatives:

• no file saving :)
• server require to serve .styl files

If it is needed to serve some backend for Stylus->CSS rendering, I will happy to serve it for free, of course.
