- Fixed bug in POP3 protocol handling, which in some cases (mail.ru) caused loading icon to be shown "forewer".
- More smart marking messages as "un/read": if there're unread messages among the selected ones, then all selected are marked as read, otherwise all selected are marked unread.
- After deleting of messages, cursor is positioned on the nearest not deleted message.
- Fixed padding on toolbar buttons
