Optionally output with version suffix

[FlorianRappl]

Optionally the public path should be changed from {publicPath} to {publicPath}{version}/, e.g., for / to /1.2.3/ or from /docs/ to /docs/1.2.3/.

OPTION 1 The output structure would be changed, too, where a folder with the version would be added containing the actual index.html. The "root" folder would then have an html file that only redirects to the specific version.

OPTION 2 Alternatively, the version can be only appended on build with --append-version or similar. In this case the output is in the original folder, but the paths all changed. This way you'd build twice for a new version - once to supply the version-less output to the root folder, and once to supply the version-suffixed output to a version directory.

Personally, I'd like OPTION 1 more as it would just be a single build and I could just upload to FTP and done. OPTION 2 you can do today by just changing the publicPath, too.
