Summery: include Session state serializer and trace messages

Fixed summary.

Ideally, this issue should be split into two separate ones. One that addresses 
including session state and another including trace messages. For now, this 
being 
marked as low priority as it may slip to the next milestone so that it doesn't 
delay 
v1.0 further.

Issue 188 has been merged into this issue.

I have attached a patch for the first point in this ticket.

The patch will enumerate the session contents into the stored error object. It 
will also append it to the /details view and the email sent.

I have just used .ToString() to display the value. I could optionally put in a 
check for ISerializable but I wanted to keep it as simple as possible.
