[Dbix-class] Debugging/trace output patch

[Nigel Metheringham]

As discussed a couple of weeks back here is a patch to do 2 things:-
     1. Remove the superfluous warn location information from the
        debugging sql trace.
     2. Allow debug to be sent to a different filehandle (default still
        STDERR).

I was originally thinking in terms of replicating the DBI trace call
API, however I have stayed with orthogonal debug and debugfh methods for
simplicity and to ensure I don't slow down the common case (no debug
occurring).

There is some DBI trace-like environment variable magic handled in
new().  Eg
  export DBIX_CLASS_STORAGE_DBI_DEBUG="1=/tmp/trace.out"

sends the debug output to the file /tmp/trace.out

POD updates are included.

Let me know if you hate it and want it changed :-)

	Nigel.
