In the confirmation prompt, tell which folder we are emptying.

Currently, when we empty the trash, it says:

"Delete all messages
All messages stored in this folder will be permanently deleted.
Are you sure you want to delete all messages in this folder?"

I would like that "this folder" be replaced by "trash".
Also in the other folders it says:

"Are you sure you want to move all messages in this location to trash?"

I would like that "this location" be replaced by "<name_of_the_folder>".
This to prevent costly mistakes.
Microsoft Outlook does this, for one.
