[PATCH 1/2] api: do not fetch every patch in a patch detail view 404

[Daniel Axtens]

mpe and jk and sfr found that the OzLabs server was melting due
to some queries downloading every patch.

Turns out if you 404 the patch detail view in the API, d-r-f attempts
to render a listbox with every single patch to fill in the 'related'
field. The bundle API also has a similar field.

Replace the multiple selection box with a text field. You can still
(AIUI) populate the relevant patch IDs manually.
