General-comments package cleanup
Plans:

1) Remove references to acs-messaging. Just store comments in the CR as a new
   general-comment content type.

2) Add package_id so general-comments can be mounted more than once and 
   comments belong to the package instance.

3) Move most operations to tcl API so other packages can add comments
   in their own way. 

4) Add support for attachements using raw CR items, use parent_id = comment_cr_item_id simple!

5) Add notifications support, per package instance, per object, what else?

6) Add support for threading using parent_id of cr_items. Make it optional, of course. (I think this already works 2008-10-28 DAVEB)
