we don't use them.
	Removed Brahms because it's huge and of bad quality.

	Started the removal of assetml. Now in the core, all sounds are assetml free.
	Improved the function gcompris_find_absolute_filename() to support a $LOCALE
	tag in a string. It will be replaced by the current locale when found.

	Next step is to remove assetml from the activity and dataset, then from the API.
