Sourcemaps relative path doesn't work if modules are inside subfolders

[benib]

Commit aaf3cc9 introduced relative sourceMap URLs. This is a problem if there are modules inside subfolders.

I don't see a very good solution, that's why this is only an issue and not a PR.

I think having absolute URLs for the sourceMaps is the better option here, as they are probably mostly used during development, and then we can use gulp watch to have a webserver with the correct root.

Any other suggestions are very welcome.

@AshleyGrant I think you created the original PR to make them relative. Can you provide some feedback on this?

@benib I've created a PR #113 to switch to inlining the source in source maps. This should resolve any further issues as it is the recommended way to handle source maps. I tested it using modules in sub folders as well as when serving the site from a folder that isn't the server base.
