org-info.js: new navigation history

[Sebastian Rose <sebastian_rose@gmx.de>]

Hi,


just cannot resist posting this here:

The navigation of org-info.js has been improved quite a bit.

  1.) Navigating a file through org-info.js, either using the mouse or
      using the keyboard, modifies the location. Thus, once you left
      the file by following a link somewhere else, your browser's `back'
      button will bring you back to the point you left the file.

  2.) org-info.js now navigates accross files. If those files both use
      org-info.js, you can navigate back and forth. Because of the new
      technique in 1.), both files nearly feel like beeing one and the
      same file. Thus following links in published files feels like
      following footnotes and returning to the context.

      Example:

      Once you reach the end of the internal history, repeatedly
      pressing `B' or `b' takes you forward and back in the browsers
      history.

      - open one of your published org files.
      - press `n' until a you reach a section, that has a link to another
        file in your published tree.
      - follow the link by clicking on it.
      - in the other file, navigate using `n' and `p'...
      - go back in the navigation history using `b'
      - repeat this, until org-info.js brings you back to the file you
        opened in step 1. Note, that you see the same section you saw
        just before leaving the file by following the link.
      - Now press `B' until org-info.js brings you to the other file
        again.

One flaw though: the internal history is lost when returning to a
file.



Regards


   Sebastian
