Implemented support for ILL requests in VuFind core code and VoyagerRestful and Demo drivers.
Added displaying of "in transit" information to ILL requests list and support for it to Demo driver.
VoyagerRestful: Implemented faster loan renewal that also works for UB loans. Implemented a faster pre-check for renewability eliminating the need for checkUpFront parameter. Added origin library to the display of UB loans.
Fixed a comment in VoyagerRestful.ini to point to ILLRequestSources properly.
Added support for displaying remote loans and requests to the Demo driver. Changed checkedout.phtml to use renew_details as the checkbox id like hold cancel check boxes already do, as there might not be unique resource id available for all the loans.
