Support for local websites

[paulozoom]

Problem

The proposed URL for checking websites, (http://cssprefix.com/[URI]) doesn't work with local web pages, either with a local webserver or plain file://.

This means that the developer needs to:

1. Publish the website with incomplete CSS prefixes.
2. Run the website through CSS Prefix.
3. Download the updated code.
4. Update their CSS.
5. Re-publish the website.

This is a sub-optimal workflow. If CSS Prefix supports local web pages, the first deploy of the website could already have all the needed CSS prefixes.

Possible solution

I believe there are three ways to do this:

1. Pasting the code to CSS Prefix
2. Uploading the code to CSS Prefix (drag & drop would be nice)
3. Developing browser extensions.

Browser extensions are able to do cross-domain requests, but I'm not sure if they can make requests from file:// websites.
