ModernTabs

General

• split the banner part in its own part in the section config
• improved & fixed the KubeJs integration
• improved the look of the example creative tab
• add a new colored banner that also acts as a fallback if only a color and no sprite location is specified for the banner in the section
• cleaned up some parts of the code
• and many more things...

Technical

• deleted the ModernTabs.Builder class in favor of the new TabDesign class
• correctly load the ResourceLocations later in the loading process, so creative tabs from other mods can be better accessed
