Add support for Local file URLs

[christian-korneck]

Browser Preview Version: 0.2.5
VS Code Version: 1.30.2 (1.30.2)
Platform: macOS 10.14.2
Chrome version: 71.0.3578.98 (Official Build) (64-bit)

Trying to open a valid file URL in Browser Preview (i.e. file:///Users/myuser/myfile.html) doesn't work:

• A blank page is displayed (no error message)
• The URL in the address bar changes from file://<url> to file//<url> (i.e. file///Users/myuser/myfile.html)
• the title bar changes to Browser Preview (http://file///<url>) (i.e. Browser Preview (http://file///Users/myuser/myfile.html) ).

The same file URL works in Chrome.

I have a similar error, but with blob:// files.
Debug console output:
Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME [blob:http://localhost:3000/72334931-d3fd-41ac-a5ba-bea316cee06b]

@auchenberg @michellocana Same here. Browser is not able to read blob URL's. Attaching screenshots.

Same URL works find in chrome.

@auchenberg I can see that in your extension.ts file, localResourceRoots property has only allowed access to the extension build folder also as per the API, it should have access to current workspace. Not sure why blob:http://localhost url's are not working.

Only reason people are still using Brackets. Fantastic Live Preview that is second to none.
