Tighten up bare excepts around the codebase (would also fix E722 warnings)

[Horgix]

There are 9 bare except: in the codebase.

I won't explain why it's discouraged, because Flake8 F722 does it well already.

This could be solved by either really thinking about what the Exceptions trying to be caught are, or by using except Exception: instead to improve things slightly.
