Fixed an issue where the login dialog breaks with ChoiceAuth if CSRF check fails for any reason (like session timeout).

Encode the username, so spaces in the username don't throw an error.

- Was out of sync with actual configuration.

- Use a timestamped init function name in Piwik tracking and load the tracking js only once. Fixes an error in lightbox and record tab tracking (Piwik logs to console: "A siteId must be given to add a new tracker").

- Resolves VUFIND-1202.

Per Mailing list recommendations adding in support for checking if the item has a location set, even if the authorized value isn't set.

- Loosened a comparison to make default pickup location selection work properly when request groups are in use.

- Fix a problem where ajaxLoadTab fails to load a tab when the domain name begins with the VuFind path (e.g. http://vufind2.local/vufind2/Record/something). 

Added missing fullstops for delete favourites messages (all latin-based languages and Russian) (#806)

- Change the static date of 2099, to the date the item was lost,
as the due date.

- eslint issues
- hidden checkboxes were not toggling correctly, so functionality was broken
