Title: in cedar-14, we need to install a java runtime for yui-compressor

since cedar-14 doesn't have java in the stack image, we'll vendor one in when we detect yui-compressor.

> The YUI Compressor is written in Java (requires Java >= 1.4) and relies on Rhino to tokenize the source JavaScript file. It starts by analyzing the source JavaScript file to understand how it is structured.
