- Removed the contact names cache (memory leak)
- Changed Contacts.searchByAddress() to Contacts.getNameForAddress(). Cursor is now immediately closed.
- Only try to resolve contact names when "Global settings" -> "Show contact name" is checked
- Never resolve contact names if number of recipients exceeds a threshold
Don't export the formatted date through the content provider: now exported as the raw Epoch value - date formatting is a UI concern. That makes MessageInfoHolder lighter.
