I was just importing 0.5 data into a 0.6 MySQL table via --migrate and 
painfully learned that each duplicate key on input will abort the whole 
process.

The (hopefully, depending on ML settings) attached patch modifies the 
--migrate task and associated test so that duplicate keys get silently 
dropped. I'm happy to commit it myself if that's ok but it seemed to me 
that ist was customary for Osmosis stuff to be discussed and then 
applied by Brett.

One could probably also have created a new --filter-duplicate-tags task 
but since 0.5 does allow duplicates and 0.6 does not, it seems to be a 
natural component of migration.

Bye
Frederik
