Better setup and teardown

• Prevent double destroy in the event of quit() being called
• Make the destroy() process a good deal more reliable
• Add a timeout parameter to new() to control how long to wait for the server to spin up/down
• Improve documentation, fix broken links
• Adjust auto-install process to work better on windows, and not leak stderr in some contexts.

Adjusted for new PW Spec

Looks like things changed out from under us since I wrote this. This release should fix that.
