Actor Editor improvements

[KR155E]

• Move extra properties and logic out of the components list and into a configuration panel
• Externalize „materials“ to be able to share textures/charsets/tiles with other actors (Actor -> Texture -> Charset -> Tiles/Map)
• Tiles/Tilemap inspector
• Add depth map support for sprites
• Add 3D Model as possible sprite source
• Add "enabled" flag to components
• Add ability to have folders, and option to merge wireframe meshes by folder (mind displacements when merging)
• Tool to scale up/down a wireframe mesh’s size
• Wireframe mesh OBJ import
• Add support for other MBgMapSprite modes, not just 1x1
• Support custom Sprite allocators (e.g. AutoScrollingMBgmapSprite in Play Novel)
