[IMP] web: x2m list: conditionnaly hide a column

This commit introduces a new way to hide a column in a x2m list view.
The attribute 'tree_invisible' can be add in the field attrs in the x2m
view definition. This attribute can use the 'parent' key to make a reference
to the parent record (e.g. 'parent.id').
