[VuFind-Tech] PATCH: allow users to broaden (or "de-narrow") their narrowed searches

[Chris D. <ce...@ui...>]

Hi all,

Currently, when users narrow down their searches via facets, they are
allowed to "undo" them all by clicking on the "road block" icon.  This
feature could easily be expanded upon (pun not intended).  This simple
patch allows users to choose to broaden (i.e., undo or "de-narrow")
categorically, one at a time, their previously-chosen narrowing terms.
