[Reference][Form Types] Document "with_minutes" time/datetime option

The `datetime` field also has a `with_minutes` option.

Using the `single_text` widget type might not work as expected using `with_minutes=false` if the browser supports HTML5's `time` input type. Most browsers seem to only support `hh:mm` or `hh:mm:ss` formats for the value attribute (resetting the value to `--:--` if using an hour value only). This might not be the case for every browser because I couldn't find anything in the HTML5 spec that says a partial time cannot be an hour only. I've added a `caution` box for this.
