Remove Bareword Filehandles

[genio]

Use lexical file handles and ensure =cut terminates POD. Only cleanup whitespace on lines within functions that filehandles were updated in.

Please ignore all of the whitespace noise in the PR.

I've had a quick glance over this, but even ignoring whitespace, the combination of filehandle changes and code reformatting makes it hard to check.

I can't see anything obviously bad here.

@tomhukins Yea, sorry about that. You can see it a bit more easily via ff8f923?w=1

The ?w=1 addition at the end of the URL removes a lot of pure whitespace changes to help un-cloud the vision.

This PR will likely need to be re-worked once @oalders merges his PR to Dist::Zilla-ify the build.

Once he's done, I'll fix this up accordingly. I would suspect the meat of the changes to remain the same, so any review is still appreciated!

Great stuff!
