The less-imports.js was being shipped in the contrib/ directory. While

fine for development builds and eggs, it didn't work at all for wheels.

To fix this, less-imports.js has been moved into the package alongside

the custom LessCSS compiler, and the path has been updated to point to

this.

Tested this on the build server. Before this, the build was failing

since the script could not be found. After, it successfully found the

script and executed it.
