Tests are not part of the core logic of Hyde, and they should not be
packaged as such.

*   Remove `hyde.fs` use `fswrap` package instead.
*   Remove logging functions from `hyde.util`. Use `commando.util`
    instead.
*   Remove `hyde.loader`. Use `commando.util.load_python_object`
    instead.

Node.js tools may be installed in /usr/bin if installed by system
package tools or in ~/bin if installed by a default installation of npm.
