global: mass rewrite to use modern exception syntax...

global: mass rewrite to use modern exception syntax Python 2.6 introduced the "except type as instance" syntax, replacing the "except type, instance" syntax that came before. Python 3 dropped support for the latter syntax. Since we no longer support Python 2.4 or 2.5, we have no need to continue supporting the "except type, instance". This patch mass rewrites the exception syntax to be Python 2.6+ and Python 3 compatible. This patch was produced by running `2to3 -f except -w -n .`.
