Provides two additional suffixes for the format filter operator.
The `duntil` format suffix returns the number of days until the (re)occurence of the specified date.
The `age` format suffix returns the age in years of the specified date.
!! Details
Currently the only supported date format is `yyyy-mm-dd`.
!! Examples
```
<$list filter="[tag[Person]has[dob]] :sort:number[{!!dob}format:duntil[]] +[limit[5]]
">
Birthday of <$link to={{!!title}}/> in {{{ [<currentTiddler>get[dob]format:duntil[]] }}} days.
<br>
</$list>
```
!! Caveats
```
<$view field=dob format=duntil />
```
Does not work, formats are hardcoded in the `$view` widget.
