- New window option monitor-content to search for a string in a window, and

highlight the status line if it matches. - To make this possible, the function cmd_find_window_search from cmd-find-window.c had to be moved to window.c and renamed window_pane_search. - While there use three new functions in server.c to check for bell, activity, and content, to avoid too much nesting.
