Add a second action menu to IssuesController#show. (#4331)

Will have the update, log time, watch, copy, etc buttons.  Had to rework
how the watchers button works since it requires a unique DOM id for the
Ajax response.  Also modified the WatchersController to be able to replace
multiple sections of the page, e.g. two Watch links.
