Editing a created keyword rather than creating a new one has also
happened to me.

The attached patch adds a checkbox to keyword.item.html
to set a __redirect_to argument to point to the current
url (create keyword page).

It also adds support for handling __redirect_to to NewItemAction::handle().

By default it always turns on the "Continue adding keywords."
checkbox. I don't know if this is the best option. Do we need:

   a per user setting added to the user class/object
   do we need a tracker config setting to determine the default state

or is setting it to on the most likely desired option (which I think it
true).

Also I plan on adding this to all "keyword" items in the default
trackers except maybe the jinja based one.

Quips, comments, evasions, questions or answers?
