Warnings about missing fuzzy config

[jdisanti]

After creating my initial config, I started seeing the following warning on startup:

15:59:40.179 CMD [WARN] Using default fuzzy config.  failed to parse global config: missing field `fuzzy` at line 1 column 10

I didn't see anything about this field in the documentation, so I read through config.rs to see what I was missing, and it looks like there's a non-optional fuzzy config? I tried adding this to the bottom of my .config/tab.yml:

fuzzy:
  - create_tab: true

Which results in:

16:23:23.706 CMD [WARN] Using default fuzzy config.  failed to parse global config: fuzzy[0]: invalid type: map, expected a boolean at line 9 column 21

Running tab --check doesn't reveal this error. If I remove the hyphen before create_tab, then the warnings disappear.

Should fuzzy be an Option<FuzzyConfig> in Config to avoid these warnings? And should the tab --check command detect these kinds of errors?
