tpl: "int" func should handle template.HTML input

[jpap]

Constructing a string from a string array fails:

$array := "1,3"
$values = split $array ","
$str := delimit (last 1 $values)
$int := int $str

It however can be done using printf which indicates that the above may be a bug:

$array := "1,3"
$values = split $array ","
$str := delimit (last 1 $values)
$int := int (sprintf "%s" $str)

I tagged this as upstream as I'm thinking that cast.ToIntE could detect a fmt.Stringer interface if not a basic type. However, we may need to just put template.HTML handling into Hugo.

@moorereason is this fixed?

[moorereason]

No, I'll send a PR to fix this.
