pylint #100707 Add check for "except Foo or Bar" [validation pending]

I've seen a pattern used where someone wants to catch either of two exceptions, so they will write

except Foo or Bar as e:

when they mean

except (Foo, Bar) as e

I have a patch which adds support for this check, and will attempt to attach once created.
