Leveraging Script URL Rewriting for SWF Path

[dominicbarnes]

This PR depends on componentjs/builder2.js#64 and adds support for a relative swfPath thanks to a feature of the builder. If the other PR is rejected, this will be closed as well.

For example:

Clip.swf("/public/component/clipboard-dom/v0.0.5/ZeroClipboard.swf");
// would become
Clip.swf("/public/" + Clip.swf());
