Allow editing "name-based" lists

[chazlarson]

If you add items to a list that result in bad matches ["Carrie (1982)" appears on Trakt as "Carry on Pickpocket (1982)", for example], there's no way to get rid of them. You can remove them from the Trakt list, but the next time Listrr updates the list, it'll get readded. If you delete the list from Listrr, it gets deleted from Trakt.

I worked around it in this initial case by exporting the list as CSV from Trakt, then deleted the list from Listrr and and recreated it using the list of titles and years as it came from Trakt [had to do a little processing to get it into the right format].

This would be simpler if one could edit the list of names in Listrr after the list is created.

An alternative might be to allow one to disable updates for a given list.

I see that issue 93 says this is implemented, but my one name-based list has only "Show" and "Delete" under the actions.
