[PATCH] Make notmuch-show 'X' (and 'x') commands remove inbox (and unread) tags

When closing a thread view, mark the thread as archived by removing
the "inbox" tag, and for the 'x' variant, the "unread" tag as well,
then kill the buffer and update the search window view as well.

This makes 'x' much the same as 'a', but instead of taking you to the
next message, it takes you back to the search window instead.

This adds new functionality without removing any; without this patch,
the 'x' and 'q' commands do the same thing,  killing the buffer
without clearing any tags. With this patch, the 'x' command clears the
inbox and unread tags from the current message and returns to the
search index view, while the existing 'q' command continues to provide
old behaviour.
