Localize UI strings derived from non-UI objects

[octo]

This ticket is being written for 2.1 due to the desire to keep 2.0 in string-freeze while its translations get brought up to date. Some of the issues here also require code changes that are a little more extensive than what is desired for 2.0.

There are several user-visible strings within LogicMail that are not directly error messages or UI element labels, and they are not currently localized. They are sometimes generated inside the object model, setup wizard, or provided by mail servers. However, it makes sense to implement separate "display names" for them that are localized.

These strings are:

• Local account name: "Local Folders"
• Local folder names: "Drafts", "Outbox", "Sent", "Trash"
• "INBOX" folder (even if the IMAP protocol explicitly specifies this English name as what the server-side will always send)
• "Default" as the name for the default identity in the setup wizard

Any other such strings should be added to this ticket as they are discovered.
