- Move block checking to higher-level code for simplicity/consistency
- Expose public method for blocking requests so message can be displayed to user
- Show account blocks on profile/checkedout screens.

- Use jQuery to handle data attributes (needed for IE 9/10).
- Fix issue with all IE versions where Recaptcha dialogs don't accept any button presses.

- added js-code to update slider when values are entered into input fields
- added check for NaN if non numeric values are entered

- avoids the possibility of calling handleUpdate for the modal before it's actually shown.

- Use the tag_id instead of a hard-coded 1 as the is_me value; this is simpler and still works because all the template cares about is checking for non-null values.
- This works around a problem in some versions of MySQL where the hard-coded 1 was causing invalid results to be returned.

- Although the ILSDI API has long declared support for comments and expirydate (or requiredByDate) in holds, as one can see in https://github.com/Koha-Community/Koha/blob/master/C4/ILSDI/Services.pm as of the time of writing, the actual call to the AddReserve function nulls any data passed via the URL. Because of this, extraHoldFields, for the time being, should not contain comments or requiredByDate because data entered by users in the relevant fields of the VuFind hold form will be discarded.

- The check is mainly required for certain old buggy Koha versions that allowed multiple holds from the same user to the same item via ILS-DI.
- In addition, it presents an error message to end users in case the hold could not be placed on an item because it already existed (even in cases where Koha ILS-DI erroneously does not return an
error code).

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