Exposed filters: remember non-visible filters

This needs thorough review before going in.

Since we need to "emulate" values which are not in the option list, but we want the same form element name, we add hidden form values as text strings.

Doing this, we need to be sure we do not introduce any security issues before committing...

Tested and worked very well!

Added check to ensure we only alter views_exposed_forms for views which actually use facets exposed filters.
