i used the destroy python function. the issue is really dropped from the database,

but all files (msg,files) are still on the filesystem. they should be dropped also to cleanup.


i know that it's not the prime idea to delete in roundup, but in our situation, we need to delete the data (also for our security).

As long as the bug is open, we need the information in screenshots and files. but after the issue is closed we should destroy all data, with any information in it. 

We should probably implement a destroy method on FileStorage and have that be called from the db destroy method. This shouldn't be too hard to do.

However, destroy doesn't seem to work at all on anydbm, so I'll need to fix that first and add some unittests.

Fix checked in to CVS. The destroy will check whether there are FileStorage elements and remove them.
