Emmanuele Bassi 79acb088e7 Remove mentions of the FSF address
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.

Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.

As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

* SECTION:clutter-scriptable
* @short_description: Override the UI definition parsing
*
* The #ClutterScriptableIface interface exposes the UI definition parsing
* process to external classes. By implementing this interface, a class can
* override the UI definition parsing and transform complex data types into
* GObject properties, or allow custom properties.
*
* #ClutterScriptable is available since Clutter 0.6
