[PATCH 2/2] contrib: pick: thread tagging (including archiving) implemented

[Mark Walters <markwalters1009@gmail.com>]

Previously pick had no actions based on the entire thread: this adds
some. Note in this version '*' is bound to `tag thread' which is not
consistent with search or show. However it still might be the most
natural thing (as it is similar to running * in the show pane).
