Introduce map_deep(), a utility function that recursively maps a callable function to every item in an array or object. Works like array_walk_recursive() but works with objects too.

Browse Source 
Updates `rawurlencode_deep()`, `urlencode_deep()`, and `stripslashes_deep()` to use `map_deep()`. Introduces `urldecode_deep()` for completeness.
