[Feature req] Creators and superusers add additional info to tasks

[massey21]

It would be awesome if tool superusers and the user who created a task could update or append additional information to the task. All of the alternatives are ugly -- duplicate tasks, excessive emails, lost information!

For my facility, I wouldn't even mind if any user could update any task, but I can understand how this level of openness might not be desirable in other facilities.

technically speaking, this would require:

• a new url for update of a task by a user
• validation that the task was created by the user
• validation that the task is pending (not cancelled, not resolved)
• use TaskForm to set the new description and use the save method of the form which already has code to set the last updated by and time as well as the updated description
• update tool control and kiosk pages to allow update by the task creator, showing a text area when the user clicks on "update" with a confirm button (see outage_details.html for an example)

this would allow users to add to the description, but not to modify what was already entered (they can always cancel it).
