recipetool: create: add new optional process_url callback for plugins

Add a new process_url callback that plugins can optionally implement if
they which to handle url.

Plugins can implement this callback for example, to:
* transform the url
* add special variables using extravalues
* add extra classes
* ...

If a plugin handles the url, it must append 'url' to the handled
list and must return the fetchuri

No functional changes expected for plugins non implementing this
optional callback
