Approve multiple texts at once

I've got this request from many Rosetta fans. Mass operations directly in the text list. I've started with the approve operation, which doesn't need any validation. There are some restrictions though:

• only texts that have less then 100 characters
• only texts that don't have an access key

As you can see in the image, the idea is simple, select a suggestion to approve for each text and click "Approve all selected suggestions". In this mode, the column context is always shown, as it's useful for approval and the actions column is hidden.

I'm thinking also of mass vote and mass add operations. Voting shouldn't be a problem, but adding should, because plugins validate the added suggestion and have to display a message somewhere.

Personally I'm not happy about mass operations as they bring errors with them, but sometimes they may be useful if the right people use them. Like when you're approving a batch of search results for a term, let's say "File". So for this mass operations there's a special permission separate from the normal operations that can be give only to some people.

This feature is on the trunk and subject to change. Any opinions are welcomed.
