- Resolves VUFIND-1223.

Voyager: fetch return date only for items that have the ’Discharged’ status and simplify the date/time handling. (#935)

- Requires significant rearrangement of table object constructors for consistency.

- Improves forward-compatibility with ZF3.

- Added support for fetching VuFind account in ILS login primarily by the patron ID that the ILS driver returns. This allows long-term consistency if other user details like barcodes change.
- Note that this new field is currently ONLY populated when ILS authentication is used; it is ignored under other circumstances.

Added en-gb.ini to CreatorRoles and HoldingStatus so that the translation of these text domains work also when ’en’ is not the fallback language.

- Mostly cosmetic adjustments
- Hides some bulk action controls (unlikely to be used in mobile) to save real estate

# Conflicts:

* * always map paia fee.about to vufind's title field as the about field usually contains information about the fee in general in case no matching record can be found for the fee

* * updated PAIATest with new mapping

Remove autofocus from searchbox to prevent autocomplete covering in various situations. Added JS to autoselect on the search home screen.

- More progress on ZF3 preparation.
