Bugfix for pulling jars locally and use facter to get facts about the host rather than relying an external source.

Occasionally the code that copied files from local repositories would fail to completely copy things; that's fixed now.

Also, if we want to be used to configure things, we need to have host info or were crippled. 
Rather than make ourselves reliant on an external source, we'll just leverage facter and use that to grab what we need. Someday maybe we'll generify this and allow ohai too but for now something is better than nothing.
