Better docs for deploys
Fix #8 (unable to read resource)

See https://github.com/boxuk/jslint-jenkins-plugin/issues/8
The 'fix' that had been put in to make it on Windows worked with older
versions of Jenkins, but as of 1.519, it errored. I don't know if this
breaks things for Windows, but at least it'll fix it for Linux.
Honestly I have no idea what I'm doing with maven...
