Use Gradle config cache

[raoulvdberge]

Describe your enhancement

Update Loom so we can use this.
Also configure configureondemand:

org.gradle.configureondemand=true
org.gradle.caching=true
org.gradle.configuration-cache=true
org.gradle.configuration-cache.problems=warn

While doing this we should also use the new recommended way of using processResources so we can use run using IntelliJ:

Should also use Modmuss' new gradle plugin for publishing, as Minotaur doesn't work with the config cache:
