Typos in variables, methods & options

[JesseWeinstein]

Here are some typos I've noticed:

https://github.com/sampsyo/beets/blob/master/beets/ui/commands.py#L443 def _summary_judment(rec): should be def _summary_judgment(rec):

https://github.com/sampsyo/beets/blob/master/beetsplug/play.py#L44 'warning_treshold': 100, should be 'warning_threshold': 100,

I'll submit a PR to fix them soon.

Agh; so embarrassing! Thanks!

Yup, I'm the one to blame for the second one. Just let me check if there are more instances of this particular spelling mistake.

E:Ok, I misspelled it systematically.

You can base your PR on top of fix-typos

Yeah, I just saw it. I'd suggest we just support both config keys, for backwards compatibility.
