Title: Fix security info display issues for Enigmail

I found some missed test cases of security info display and have fixed issues.
Is it possible to add a hook in conversation.js?
Thanks.

- Fix security info display isn't updated when a thread has several
messages and one message in the thread is selected at expanded message
list. This fix adds a hook "onFocusMessage" in conversation.js.

- Fix clicking a link fails when show/hide of security info happens and
the link position is moved while clicking.

- Fix security info display isn't updated if using keyboard shortcut
'f' or 'b' in conversation view.

- Fix getting wrong charset when several unread messages are streamed at
one time and messages have different charset from each other. This
issue causes verification signature failure.

- Add forgotten substring().
