LP#2018615 - LookupUser Password Auth

Adds support for checking passwords or PIN in the LookupUser message.

* Supports making passwords mandatory for the LookupUser Message.
* Supports auth-proxy with similar options as LP#1526558
* Includes a fix for the oils_ncip.xml config error mentioned in readme.
* Includes some testing messages from the Folio.org mod-ncip project.
  * https://github.com/folio-org/mod-ncip/tree/master/docs/sampleNcipMessages

oils_ncip.xlm fix - seems like as long as there is one non commened
out entry in a section, then the bug that would put the commented
out portion in the config data doesn't get triggered.

I haven't tested any of the auth-proxy settings since I don't
use that.  But I enabled the option and can confirm that
it still seems to work even when the auth-proxy enabled api call is
used to check if the feature is enabled.

Tested LookupUser Messages
* Barcode only
* Barcode and Password
* Barcode and PIN
* Barcode only with lookupuser_require_password enabled.
* Barcode and Password with lookupuser_require_password enabled.
