[netcdf-java] Special toolsUI 5.9.1.1 release

Greetings!

We encountered an issue in the netCDF-Java 5.9.1 release in which the
toolsUI jar would sometimes get created without a critical properties file
being included. Unfortunately, the toolsUI 5.9.1 jar did not have the file
included, and as a result, the application fails to launch. The build
system has been updated to ensure this file is always included, and a new
toolsUI only release has been made (v5.9.1.1). The jar can be obtained from
the NSF Unidata netCDF-Java downloads page
<https://downloads.unidata.ucar.edu/netcdf-java/> as well as the github
repository release page
<https://github.com/Unidata/netcdf-java/releases/tag/v5.9.1.1>.

Cheers!
