Comment 6 for bug 1349906

I enhanced the tasklist plugin a little further.

#Changelog:
Within the dialog, there are now 2 additional columns available for Tags and Comments. The text within
the comment column is auto wrapped.

I removed the tags from the tasks and display them within the additional tag column.

The comments to tasks (from the comments plugin) are now collected as well and displayed within the comments column.

Example:

[] Implement the possiblity to tick tasks within the plugin [d:2017-03-31] @GüvenMurat
   * comment: [2017-03-07]> Additional column needed
   * comment: [2017-03-07]> Ask Jaap about the index implementation

I also integrated following plugins into the tasklist plugin:
* Tag auto completion
* Task comment
* Task Due date

If you use them already, you should deactivate them.

Please let me know if you find any issues.

@Jaap: I also want to implement the possiblity to tick the tasks within the plugin. I looked through the index implementation but don't grasp it completely. I wonder if I can take the source id within the tasklist index and get the related page file to read and parse again for tasks and replace
UNCHECKED_BOX with CHECKED_BOX?
