On C-c e j the current exporter just exports to tj2. On C-c e J it opens
the TaskJuggler GUI (which compiles and visualizes). Now for tj3 I would
assume that a corresponding action would be to let tj3 compile the
exported tjp file and open the resulting reports(s), be it in a browser
or a text editor. In theory we would probably need another key binding
to just compile the tjp file. This is similar to the LaTeX exporter
where you can (1) just export, (2) process the exported LaTeX and (3)
open the resulting PDF.

Opening report files (text or html) should be fairly simple using
org-open-file. The hard part is knowing what files to open without
having to parse the report definition to figure out the file names.
Maybe the output of tj3 gives a hint what report files were produced.

Currently the way to define reports is through the customize variable.
But this is then used for all taskjuggler exports. To support file
specific reports I was thinking that we should use the #+BEGIN_foo
mechanism, i.e. introduce a TaskJuggler blocks with #+BEGIN_TaskJuggler
and #+END_TaskJuggler. These could then be used for example to define
reports. This would require some changes to org-exp.el.

Thoughts? Ideas?
