views: patch-list: show the 'Properties' update box for all users

Any authenticated user should be able to change the properties of their
own patches from the list view. They can already do so from the patch
view and from pwclient.

Now, authenticated users can perform 'Change state', 'Delegate to', and
'Archive' operations on multiple patches at a time (e.g., after
'select-all' on a bundle, or after selecting a few patches
individually). We'll print an error message to the page for any patches
which can't be updated (e.g., due to ownership).

This fixes a usability issue that has been reported a few times.
