Revised the way that exceptions are thrown around. Instead of context being a

complicated string of pointers, it's now just a global block of text that gets
appended to as the error is being thrown up, and can be displayed at the catch
point if desired.  There are almost no cases where a thrown exception will not
result in an error message being displayed to the user.
