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.

-   `include_file_patterns` property accepts globs to filter by file name.
 -   `include_paths` accepts paths relative to content.
 -   `begin_node` and `node_complete` honor `include_paths`
 -   `begin_text_resource`, `text_resource_complete`, `begin_binary_resource`
      and `binary_resource_complete` honor both.
