Draft: Attempt to fix build

[jtaub]

• Update to Java 17
• Remove dependencies on non-standard (non-existent?) repos like com.javassh
• Removed the raster plugin, which could not be found in any standard repo
• Replaced any -SNAPSHOT dependencies with actual versions

This allows me to run the application locally using Intellij, and it is able to detect my Razer Naga mouse. Has plenty of bugs though, such as an instant crash and inability to start if I change themes, for example.

mvn clean install still fails to succeed, failing to compile because of module not found: org.jnrproject.enxio
