[daisy] Daisy detachment - update

[tim_cranfield at goldenboat.net]

I have committed some updates to the detachment project to 
address comments from the August mailing list.

Most significantly, the gui now has a single tabpane for each 
detachment, and the documents and their contents are all 
displayed as part of a tree, similar to this diagram from
http://lists.cocoondev.org/pipermail/daisy/2006-August/004755.html:

+----------------------------------------------------
|  myfile                  [x]
+----------------------------------------------------
|  myfile.ddz              |   this panel should then
|  |-- meta                |   show some details
|  |   |-- connection      |   and possibly some editor
|  |   `-- other info?     |   (for fields) or action
|  |-- [id] docName        |   buttons (launch editor)
|  |   |-- parts           |   corresponding to the chosen
|  |   |   `--  ImagePart  |   item in the tree
|  |   |-- fields          |
|  |   `-- links           |   As 'details' you could
|  |-- [id] docName        |   be showing meta-data info
|  |   |-- parts           |   like part-size and mime-type
|  |   |   `--  HTMLPart   |   and what not that could be
|  |   |-- fields          |   useful in debugging.
|  |   `-- links           |

This now means detachments are closed and uploaded as a single 
unit, rather than dealing with individual documents.

I also followed Bruno's suggestions for html cleaning 
http://lists.cocoondev.org/pipermail/daisy/2006-August/004761.html, 
and that seems to be working now.

Some things that still need to be done:
1)Creation of an installation program
2)Finding the best way to use jdic, refer:
