Add filter for taxonomies shown in quick edit

[helgatheviking]

I'd like to propose that there be more options to adjust the default quick edits. For instance, my Radio Buttons for Taxonomies plugin removes the default metabox for taxonomies and replaces it with one that uses radio inputs, which limits the user to a single term choice.

However in the quick edit, this is easily circumvented, because I have no way to remove the taxonomy inputs from being displayed in their default ways.

At the minimum, just adding a filter to the taxonomies would let me disable the default taxonomy inputs and then add my own. More hooks/filters would be ideal, but I think this is the minimum I can get away with.

Sorry it isn't a patch or diff... I'll try to get WordPress set up as a repo on my computer. But in the mean time I'm proposing a change to :

/wp-admin/includes/class-wp-posts-list-table.php file

in the inline_edit() method, for instance, i'd like to change

$taxonomy_names = get_object_taxonomies( $screen->post_type );

to:

$taxonomy_names = apply_filters( 'inline_edit_taxonomies', get_object_taxonomies( $screen->post_type ), $screen->post_type );

[helgatheviking]

adds a filter for the get_object_taxonomies in inline_edit
