[development] Deletion API

[Chad Phillips -- Apartment Lines]

normally i wouldn't post request for feedback on an issue here, but  
this is a sweeping change, and it needs eyes on it!

Deletion API for core: The deletion API will provide a standardized  
method through which deletions from the database can be managed more  
completely. It offers several hooks, both prior to deletion, which  
allow outside modules to display messages on a confirmation screen,  
process the data prior to deletion, or abort deletion altogether.

the issue: http://drupal.org/node/126300

a very kick ass demo site, with theory, workflow, links to the code  
that makes it work, and it also serves as a test site for checking  
out what it can do as of today:
