Minor Update to v1.24.3 (All builds)

We have updated the Vernalis plugin to v1.24.3 on the trunk (nightly) and stable (KNIME v 3.7.x and 4.0.x) builds.

This is a very minor update which allows the use of the latest RDKit community contribution version (v4.0.0; currently only on the nightly build) with the our nodes. Thanks to @manuelschwarze for bring this problem to our attention.
