KNITRO: update UCL LM as Economics have renewed the site license [1466272]

We look after the LM for KNITRO so it can be run on Myriad.

Economics have renewed the site license for another year and there is a new version of the LM software. We are currently running 13.2 and 14.1 is available. The latest version is needed to license versions of KNITRO after 13.2.
