[Zope] confera, zope 2.2, and attachments

[Cary O'Brien]

(Vitaly (vos@telenor.cz) helped me with this.  The problems was
that it wasn't possible to add an attachment to a ZDConfera message)

Note this is with Zope 2.1.6. 

Thanks for the information on fixing attachments in ZDConfera.  Note that
the latest version of ZDiscussios (0.2.0) does use FileObject() in
ZDConfera.py, but it doesn't import FileObject, and the icon is wrong.
The error is masked by the try block.

So the fix I used was...

0) Get ZDiscussions
1) Get Confera
2) Cope FileObject.py to lib/python/Products/ZDConfera
3) Edit ZDConfera.py
	1. at the beginning add "from FileObject import FileObject"
	2. change "icon='misc_/Confera/attachment.gif' to 
 	          "icon='misc_/ZDConfera/attachment.gif'
4) Restart

Thanks again,
