Include symb in msgid when sending feedback about a resource.

Include an error bit in msgid (1 if message is a "bomb" caused by an error when rendering a problem.

Include symb and resource title in messsage (<symb> and <resource_title> tags) when feedback is about a resource.

Navigate Contents page now checks for unread feedback or errors using symb instead of just resource url.

Navigate Contents page checks for resource context based on symb in msgid instead of in [url] included in message subject.  Backwards compatibility with old-style messages retained.

Subject for feedback messages about resources appends message title instead of url inside [].

Title on feedback page now avoids leaking unencrypted file name in cases where no title was assigned to a resource with hidden url.

When displaying feedback messages about a resource in a course, "Refers to" link displayed when viewer has corresponding course role selected includes symb in the link. Link text is now resource title.

"Refers to" link points to unencrypted resource url if feedback message is viewed under role other than original course, only if user has bre privilege for the resource, otherwise "Refers to" link is not displayed.

lonfeedback -- Some replacement of decode_symb() and &clutter() and &dewrapper() with &get_feedurl_and_clean_symb() for replies and edits of discussion posts.

lonfeedback -- More work on in ensuring hidden urls are encrypted or unencrypted as required.
