[ALLI-2520] Modifications to PCI facets: added checkbox filters 'Full text available' (shown by default) and 'Peer reviewed'. The latter is displayed inside 'Format' facet section and is shown if it is enabled. Removed 'Availability' facet since it's options are now displayed elsewhere. If needed, also other checkbox filters (local or PCI) may now be configured to be displayed inside facet sections.
