Integrated bookmark bar. Global getter from public and private workspace.ini and setter to private workspace.ini

 Implement inline watch for get_file/save_file.
 Replace the codeeditors implementation for file change watching with the global one.
 TODO: renameing a file does not trigger the desired events (needs fix in fsmonitor)

 Includes inline-watch upon filecount/filelist if a watch_id is given.
 The watch handels are identified by window_id, view_id (both set automatically) and watch_id of choice.
 Upon changes a "watch" message will be send via bus containing further details (action, watched path, watch_id).
 Also prevent multiple filelist updates from running simultaneously and improve overall update triggering.
