First release of Source Map support

To debug original sources, Web Inspector must find a "//# sourceMappingURL=" comment at the end of the JavaScript file. That comment must contain a relative path to a local source map file. The source map must in turn have path(s) to original source files.

If things aren't working -- check for error messages in the Sublime console. Or, disable source maps from the menu ("Toggle Authored Code")

If you set a breakpoint in the generated code, it will not appear, but will be set in the original ("authored") code.
