provide an option to append/prepend wildcards
|Reported by:||bartvde||Owned by:||elemoine|
currently the user needs to explicitly provide wildcards in the form fields, but there might be cases where we want to automatically prepend / append wildcards (or even both prepend and append a wildcard) to the search string.
Not sure how to implement this though, should we add types to GeoExt.form.toFilter.FILTER_MAP e.g.
like_prepend like_append like_both
