[tasklist] ui review of tasklist

Some of the HIE's at Sun reviewed the tasklist the other day (I gave a
quick virtual tour).  This is the feedback I got.

* They were concerned about the automatic-computation of percentages
  for parent tasks. If you have a task with a single subtask, checking
  done on the subtask marks the parent task done as well.

  The recommendation is to change the default on tasks from "Compute"
  to "0 %".  Thus, if you have lots of subtasks and you'd like the
  percent complete auto computed, select "Compute" as the percentage.
  But when you have one or two subtasks, you don't confused.

* They felt the distinction between the user tasklist and the
  suggestions view was a little unclear (given that for example
  Studio .NET has a single view for these two purposes). After
  seeing how you can create multiple tasklists, how it can integrate
  with other calendar managers etc. I think it was a bit clearer,
  but this is something the documentation should make clear (the
  biggest problem was the source-task-scanner, since the user
  enters these tasks in the source code (and the New Task dialog
  refers to them) yet these end up in the Suggestions view. Also,
  not all suggestions are suggestions - the TODOs for example.
  The "Tell me How" documentation on the New Task dialog in particular
  should clarify this point.

  As a side note, we should make cut & paste from the suggestions
  view to the user task view work!

* When you export to HTML you get multiple dialogs (enter file name,
  do you want to include gifs?, file exists - are you sure?,
  do you want to show the result?).  Try to combine at least some
  of these into the original file chooser (probably not file exists
  - are you sure?).

* Some discussion on menu lengths, click-to-insert task and its
  problems, etc. I think somebody took minutes so when I see them
  I'll forward.
