[Koha-patches] [PATCH] Bug 3154 Limit facets computing on first 50 biblios

[Frédéric Demians]

With this limitation to 50, we are sure that Fridolyn patch doesn't impact
search performance.

Branch: new/bug_3154

Now someone must add:

  - The ability to increase this number via a syspref, for example
    FacetFirstBiblios
  - The ability to hide facet count by syspref, for ex. FacetHideCount
