Add version number to dist file

There are actually two versions to track here:

1. The version # of this CSS module
2. The version # of the Spectrum Responsive Grid that it is tracking against.

Locate the dist file and inspect how the CSS module version and the Spectrum Responsive Grid version are currently tracked. Confirm where each version should come from, then update the distribution output so both values are present and independently identifiable. Verify the generated dist file reflects both versions.
