VEFKUP - views exposed filters keep URL params
At the current moment views exposed filters do not respect other params in the URL except for their own. This causes conflict when using facetapi or search_api_sorts. For example if you choose some filters first and will change some exposed filters afterwards and submit the form - all the chosen facets will be lost (unselected).
So this module is aimed to fix this problem. It puts all the facets into the exposed form so when the form is submitted - all the facets GET params are in place.
