$parameters widgets now claim index parameters sequentially (#7962)

* $parameters widgets now claim index parameters sequentially

Before, they just always used their own indices, which meant unnamed
parameters would get assigned to multiple values, which wasn't any
use to anyone.

* Elaborated tests for nested parameters

* Added example to clarify how multiple paramter definitions are handled

* Updated \procedure documentation

* Removed depth from $parameters

* Add failing test

* Adjusted transclude to account for refreshing

* This index system should work

It handles some strange edge cases too.

* Stupid end-of-file newlines

* Removed redundant whitespace pragma

-		<$text text=<<currentTiddler>>/>
-	</$list-template>
-	<$list-empty>
-		None!
