Miscellaneous 20141007

- Logout link in UI
- Fix password generator script (merged in #231)
- Update distribution assembly to create directories properly
- Merge all CLI commands into single brooklyn script
- Move first member sensors to `Group`
- Fix more logout issues (but still needs *lots* more work... :koala:)
- A few other minor changes
Now the `brooklyn` script subsumes both the item lister and cloud explorer, which I think is much nicer.
