Added
- The `grid` field modifier for displaying fields side-by-side in a
responsive flexbox.
- The `tabular` modifier for the `review` block, which will cause the
items to be displayed in an HTML `<table>`.
- The `abbreviate` optional keyword parameter of the `states_list()` function.
Changed
- Altered the CSS of `radio`, `yesno`, `yesnowide`, and `checkboxes`
labels so that the text will not wrap under the bullet.
- Configuration will not save if there are duplicate keys in the YAML.
Fixed
- Avoided `KeyError` when combining `terms` and `autoterms`.
