	* stats/forms.py:
	* stats/views.py:
	* templates/module_edit_branches.html: Instead of using a 'delete'
	checkbox to delete a category, use the empty value of the release popup to
	signify 'delete'. Probably more intuitive, as old delete checkbox could be
	interpreted as the branch deletion.
	Fixes bug #575541.
