Java plug-in update

The configuration for Cascade forms, Banner, Famis, Bosscops, and Bosscars was updated to require a new version of Java. The version to be used now is 1.6.0_18.

Note: this caused some issues this morning, when version 19 was inadvertently coded to be downloaded. Several users experienced problems which required their Java to be uninstalled and reinstalled. By 9:30 am, the configuration was updated to download the correct version.
