server: copyFile doesn’t need useless params anymore
server: Save template files
gulp: Copy build libs into generated dir
example: update
Generated files can now re-regenerate their content

This is done (for now) is a parameter has been set.
Router: allow absolute paths
browser: use console directly
browser: Dynamic generation now directly loads linked pages
server: logger: Remove error handler

We don’t need it since we wrap everything in Promises
Cleanup logger
Dynamic page loading now handles arguments
Dynamic page loading now update the URL
Use global paths as soon as possible

The only relative paths are those provided by the
`url_to` helper, but they are converted into global
paths quickly, and only those are manipulated by
the application.

This change fixes many bugs dues to path considered
as relative where they should be global, or the
opposite.

- Split tasks
- Use dependencies intend of calling task manually
gulp: serve: Display URL to use
gulp: Add split `gulp` and `gulp dev`

The `gulp` command only generates the content, the
`gulp dev` command generates the lib and the content,
starts the HTTP server and watch changes.
