Added backtrace support to the Exception system. It's pretty simple, if it's

enabled, and the compiler/libc support it, then you just get backtraces, if not
you get a message about it not being supported.  It probably shouldn't be
enabled in most production environments, since it does happen for every
exception, and could be memory and time consuming.
